Daikin HiLine fan coil air conditioning units are designed for use in multiple floor apartments and office buildings, hotels, and other similar applications. They require a minimum amount of floor space and one unit may serve several rooms, thus reducing installation costs.

The 1000 and 1200 cfm draw-through configuration units described in this manual are designed for multiple discharge arrangements so that one unit can serve more than one room.

Two-pipe and four-pipe systems are available, with single, double, triple, and top discharge arrangements. Optional equipment is available to provide complete application flexibility.

Installation and maintenance must follow accepted industry practices as described in the ASHRAE Handbook, the

National Electric Code, and other applicable standards. Install this equipment in accordance with regulations of authorities having jurisdiction and with all applicable codes.

Installation and maintenance must be performed by qualified personnel familiar with applicable codes and regulations and experienced with this type of equipment.

CAUTION

SHARP EDGES ON SHEET METAL AND COIL SURFACES if not avoided could result in cuts .

Receiving and Handling

Carefully check items against the bills of lading to verify all crates and cartons have been received. The units normally ship four to a pallet.

Carefully inspect all units for shipping damage. Report damage immediately to the carrier and file a claim.

Check the electrical nameplate to be sure it agrees with the power supply available.

DO NOT handle units by the riser piping. Riser clamps hold the riser in position; they are not designed to support the cabinet weight. They are removed after the unit is installed.

Units are completely factory assembled and wired and have individual thermostat controls. They are installed by stacking one unit on top of the other. While installing, prevent dirt and other foreign matter from entering the risers and plugging lines or valves.

Installation

Cabinet

1.

Lift and position unit in place directly above the unit on

the floor below. See

Figure 2

a.

2.

Align riser extensions with risers on unit below.

3.

If field-supplied isolator pads are used, install them now before connecting risers.

4. Before anchoring the risers in place, center the horizontal stubs protruding into the cabinet in the 3

"

(75 mm) slots in the panel risers. This allows for riser expansion or contraction of plus or minus one inch.

Risers extend 5" (127 mm) above the cabinet when the stub is centered in the slot.

5.

Anchor risers to the building structure to prevent vertical riser movement greater than ±1" (25mm) due to riser expansion or contraction.

Figure 2: Installation overview

CAUTION

The unit is not designed to support the weight of the risers . Anchor them securely to the building structure .

6.

With the unit in position, check that it is level to provide proper condensate drainage and operation.

7.

Connect supply and return risers to unit on floor below

(

Figure 2 c) by soldering slip couplings (reducing

couplings, if required, are not supplied by

Daikin).

8.

Join drain riser with coupling using PVC solvent cement on both surfaces (or solder if riser is copper).

9.

Apply insulation to risers and to cement joints between units to avoid condensation problems. (Not provided by

Daikin).

10.

After the unit is installed, remove the riser ties.

11.

Restore the fire resistance rating of the structure to comply with existing building codes, by sealing the access space around the risers with material having the same fire rating as the structure. Also provide a seal between floors to prevent the passage of warm, humid air, which can cause condensation on riser insulation.

This is most critical in unpressurized buildings with high infiltration rates.

12.

Vent the coils. The vent is accessible from the return air opening.

13. Before furring in unit, hydrostatically test the riser and unit connection joints to make sure they are leakproof.

IM 168-7 5

Installation

Furring In

1. When furring in units, make sure no screws or nails penetrate the unit cabinet, other than grille or plaster frame attaching screws. Grille or plaster frame attaching screws should not penetrate the cabinet more than 2

" (51 mm).

2.

The thermostat box can be positioned up to 3-7/8" (98 mm) from the unit for furring in. The mud ring can be positioned vertically or horizontally and has 2" x 4"

opening. (see Figure 3

).

3.

If the wall board or other wall material does not fit flat against the face of the unit, install field-supplied extension sleeves for both the return and supply air openings.

Wiring

The complete unit system wiring diagram is located on the front of the access panel. Wire in accordance with local codes or the National Electrical Code, whichever is applicable.

1.

Provide branch circuit overcurrent protection and disconnect means.

2. Bring electrical wiring through the side of the cabinet into the wiring box located on the right side of the

cabinet (see Figure 3

Side View) using the two 7/8" (22 mm) diameter knockouts.

NOTE:

When routing wiring through the cabinet, make sure the fan remains accessible for possible removal .

3. Connect control wiring to the unit-mounted thermostat and fan switch or a remote mounted control.

NOTE:

A remote mounted 10 K thermistor is mounted on all units for sensing return air temperatures . The 10

K sensor is also provided with all factory purchased thermostats .

4. Rotate the fan wheel by hand to make sure it rotates freely.

Ducts

If ducts are added:

• Install in accordance with NFPA 90A and 90B.

• Check that the resistance is within the limits of the external static pressures shown in the catalog for the particular unit being installed.

• Design the ducts for velocities in accordance with the methods outlined in the ASHRAE guidebooks.

• Control airborne noise by installing sound attenuating materials and by installing flexible connections between the unit and ductwork.

Finishing

1. Attach the return air grille plaster frame on the opening over the top of the wall board. Use the wall board frame as a template to drill pilot holes into the wall or unit for the attaching screws (see Figure 4 ).

NOTE:

Mount the plaster frame with the corners square so that the grille panel will fit over it properly.

2. Attach the supplied retaining clips to the plaster frame adjacent to the lower attaching screws (see

Figure 5 ).

Installation

Twin Units Installation

Twin opposite hand units share a common riser system; i.e., supply, return, and drain riser. This is commonly called a

“master/slave” arrangement. The master unit is shipped with the risers attached. These special risers have stub-outs which must be field connected to the slave units. In addition to the instructions in bulletins IM 254 (FHSK units) or IM 255

(FHSS units), the following procedures must be followed for alltwin unit installations.

1.

The slave unit has no risers and no stub-outs. Knockout holes are provided for internal piping connections.

2. FHSS-110 and -112 units will not match up with the smaller units sizes 03, 04, 06 and 08 due to differences in riser stub-out locations.

3. Master units are offered in two-pipe or four-pipe systems with either right-hand or left-hand connections.

Secondary units are offered to accommodate internal connections to any of these riser systems or locations.

4. The riser location (right or left) is determined by facing the return air grille panel. The risers are located on either the right or left of the unit. This defines the riser

location and unit handing. See Figure 6

.

Figure 6: HiLine Twin Unit Arrangements

5. The riser block-off plates are located in the base of the slave unit. Block-offs must be installed on the slave unit

before putting it into position. (see Figure 8 on page

9

).

6. Install the master unit per IM 254 or IM 255.

7.

Recommended wall opening locations for the slave unit risers and stub-outs are shown in

Figure 7 on page 8

IM 168-7 7

Installation

Figure 7: Riser and stub-outs locations

8.

The openings must provide enough space to allow easy installation of the unit. During installation, the unit is tilted at an angle to set into place. Unless the opening in the wall is large enough, there will be interference and the unit cannot be set into position.

9. Openings must be large enough to accommodate riser stubs with foam insulation. An allowance must be made for insulation thickness, fitting connections, and hand valves on the stub-outs.

10.

The opening in the wall must provide space for vertical movement of riser stubs as a result of riser expansion and contraction.

11.

The slave unit piping terminates with 5/8” sweat connections. The piping is also supported inside the cabinet to prevent any damage to them during shipment. This support bracket must be removed to allow expansion or contraction in the piping after unit is installed.

12.

The ball valves are not factory mounted to the slave unit piping because there would be insufficient room between ball valve and cabinet to make field connections to the unit. The ball valves (quantity 2 on two-pipe, 4 on four-pipe), if ordered from

Daikin, will be shipped in a separate box. The correct installation procedure, as outlined in subsequent

paragraphs, is to first mount the ball valves to the riser stub-outs and then set the slave unit in place with the ball valves protruding through the slave unit riser knockouts. The connections can then be made between

ball valves and unit piping within the HiLine slave unit.

13.

The length of tubing between the 5/8" O.D. slave unit stub-out and the hand valve for the slave unit is to be provided by the contractor. The length will be determined by the dimension between the walls.

After the master unit is set in place, the field supplied tubing should be sweated to the riser stub-outs and ball valves sweated to the field supplied tubing. Hand valves should be closed and risers pressurized to locate any leaks. Leaks should be repaired before slave units are installed and access is restricted.

14. Stub-outs from the supply and return risers are 35

" (889 mm) on center from the bottom of the unit. They are to be made of 7/8" copper tubing for the supply and return cooling, and 5/8" for the supply and return heating. The standard stub-out length is 2-3/4" (70 mm) beyond the outside diameter of the riser.

15.

The drain stub-out is either 1/2" PVC or 5/8" O.D.

copper, depending on which was ordered for the job.

8 IM 168-7

Installation

16. Secondary unit stub-outs should be well insulated by the contractor to prevent condensation problems.

17.

Remove the appropriate riser and drain knockouts in the lower cabinet of the slave unit.

18.

Slit the fiberglass insulation so that the riser ball valves can be pushed through and into the slave unit.

19.

Install the slave unit riser block-off plates as shown in

Figure 8.

Figure 8: Riser block-off plates

20.

Position the slave unit to the hand valves. The horizontal stub-outs should be centered in the opening in the cabinet.

21.

Solder connections if sweat valves have been supplied.

22. Attach plastic drain hose to the drain line. Be sure hose clamp is properly installed and that there are no kinks in the hose.

23.

With unit in final location, check level to provide proper condensate drainage and operation.

24. Use IM 254 or IM 255 to complete the installation of the slave unit.

25.

Figure 6

shows a typical example of a master/slave arrangement for a two-pipe system. For four-pipe master/slave riser location, refer to catalog CAT 770-5

(page 15).

Start-Up

CAUTION

Prior to unit start-up, make sure no foreign material remains in the unit,paying particular attention to the drain pan and drain line . Blocked drains can result in drain pan water overflow .

1.

Remove all foreign material from unit.

2.

Open supply and return water service valves.

3.

If the unit does not have the automatic flow control option, balance the water flow rate with the hand valve on the return line.

4. Install the front access panel.

5.

Put the filter into position.

6. Install the return air grille.

7. Close all windows and doors.

8. Switch the unit to ON and check for proper operation of fans, fan speed switch, and thermostat.

NOTE:

When there is a high amount of moisture in the air, this initial pull down should be gradual to reduce the possibility of unit sweating (i .e ., high fan speed for maximum air flow with reduced GPM and elevated chilled water temperature for reduced capacity) . Do not operate outside air supplies or toilet exhaust systems until the gradual pull down is complete .

12 IM 168-7

Maintenance

Filters

• Clean filters to obtain maximum unit performance.

• Inspect filters every three or four months under normal operating conditions and replace when necessary.

• Do NOT operate units without a filter.

Drain Pans

• In areas where airborne bacteria or other microorganisms are known to produce growth in the drain pan, treat the water chemically to minimize the problem. Contact your local

Daikin representative or one of the many companies dealing with water conditioning.

• The condensate drain pan can pick up lint and dirt, especially with dirty filters. Inspect the drain pan twice a year to avoid the possibility of overflow.

Fan Motor

NOTE:

The fan motor is oiled at the factory . Under continuous operation; it is not necessary to oil it in the first six months .

• Oil the fan motor every six months with one teaspoon or

5 cc per bearing of SAE No. 20 nondetergent oil.

Do NOT overlubricate.

Coil

• The coil must be clean to obtain maximum performance.

• Check the coil once a year, under normal operating conditions. If it is dirty, brush or vacuum clean. Take care not to damage the aluminum fins while cleaning.

CAUTION

SHARP EDGES ON SHEET METAL AND COIL SURFACES if not avoided could result in cuts .

Electric Heater Troubleshooting

Daikin electric heater elements, if furnished, are designed with a high limit control set to trip when cabinet temperatures reach 175°F and automatically reset when cabinet temperatures drop to 140°F.

If the high limit temperature is tripping, the unit is not performing properly. Some probable causes are

• Not enough air over the heater due to dirty filter

• Fan motor not operating

• Dirty coil

• Fan wheel loose on the motor shaft

• Loose electrical connections

Electric Heater Removal

If the electric heater requires service, remove it as follows:

1. Shut off electrical power to the unit.

2.

Remove the discharge grille.

3.

Reach through the opening and remove sheet metal screws A and B as shown in

Figure 14 .

4. Lift the entire element out of the sheet metal frame as

shown in Figure 14 .

5.

Replace the defective part and reinstall the heater.

When requesting service or replacement parts, direct your inquiries to Daikin Service. Refer to the model number and the serial number of the heater stamped on the serial plate attached to the heater kit. If replacement parts are required, provide the date of the heater kit installation and the date of the failure. Also, describe the part being replaced and explain its malfunction.

Temperature Range: 50°F - 90°F (10°C - 32°C)

TA155: A HEAT-OFF-COOL system switch manually selects heating or cooling mode. In the HEAT position, only the heat output cycles with demand. In the COOL position, only the cool output cycles with demand. In the OFF position, heating and cooling outputs are off. Units with a two position system switch or without a system switch must use a load transfer switch when both heating and cooling outputs are used. This prevents control failure and equipment damage caused by direct cycling between loads.

TB155:

An ON-OFF system switch enables auto-changeover of heating and cooling modes. In the ON position the thermostat activates heating or cooling outputs dependant upon the relationship between set point and ambient temperature. Heat on to cool on dead band is 4°F. In the OFF position, heating and cooling outputs are off. Units without a system switch cycle between heating and cooling with a 4°F dead band.


20 IM 168-7

FAN:

Some units have a switch for manual selection of fan speed. On these units fan operation is either internally wired for fan continuous operation or is dependant upon connection to the fan supply input . When internally wired for fan continuous operation, the fan will be off when the system switch is off. When dependant upon external connections the fan may not be off with the system switch in the off position.

The fan supply input is switched to fan speed outputs (HI -

MED - LO).

SWITCHED POWER: L1 power is switched to this output any time the system switch is out of the OFF position.

Application Notes

1.

To use a remote sensor, remove jumper JP-1 to disable local sensing. See Figure 1. Failure to remove JP-1 when using a remote sensor will cause improper operation of the thermostat. Some units do not have remote sensing capability.

2.

Units with remote sensing capability have a fourposition terminal block at TB1. If TB1 is two position the unit is local sensing only.

3. Remote probe wiring should be located away from any electrical motors or power wiring

4. Some units are internally wired for permanent fan continuous operation.

Appendix

5. On units with a Fan Supply input, the operation of the fan is determined by wiring connection. For fan continuous, jumper the Fan Supply input (TB2-5) to the

Switched Power output (TB3-3).

6. For fan cycling operation with a call for heat or cool, a fan relay must be used.

7.

Observe electrical ratings. Thermostatic outputs are pilot duty only.

Saving Changes

As you navigate your thermostat, be aware of the thermostat’s save and exit protocol:

• The thermostat automatically saves all the changes you make, as you make them.

• When you are in the SYSTEM or FAN menus:

— If you push a button that is not applicable to the current menu, all changes are saved and the thermostat goes to the menu associated with the button that was pushed.

—

If the thermostat is idle for five seconds, the thermostat times out, saves all changes, and returns to the thermostat’s default display.

• When you are in the PROGRAM menu:

— If you push a button that is not applicable to the current menu, nothing happens (your programming is not interrupted).

—

If the thermostat is idle for fifteen seconds, the thermostat times out, saves all changes, and returns to the thermostat’s default display.

Up/Down Arrow Button Operation

The ▲ and ▼ buttons function in two ways:

• When you are in the default display, you can press ▲ to increase, or ▼ to decrease, the current temperature setpoint. This will override programmed temperature settings until the next programmed time period (Wake,

Turns the system off by disabling all thermostat outputs

Setback mode is an energy saving feature that minimizes the heating and cooling when the room is not occupied . Setback mode overrides the programmed time and temperature settings by telling the thermostat to instead use the setback setpoint for heating and cooling . The setback setpoint temperatures are factory default or installer-selected during installation . During setback mode, when a demand for heating or cooling exists, the fan will run at the lowest speed .

SET BACK • Automatic setback mode: If your thermostat is connected to an occupancy sensor or door switch, setback mode is automatically turned on and off by the sensor or door switch .

• Manual setback mode: Select SETBACK in the SYS-

TEM menu . Setback temperature settings will remain in effect until you manually turn off setback mode . Selecting HEAT, COOL, or AUTO in the SYSTEM menu will turn off setback and resume your programmed time and temperature settings

NOTE:

SETBACK appears on your menu only if the thermostat’s installer enabled this feature .

Programming Time & Temperature Settings

Your thermostat’s programming feature allows you to divide up a 24-hour day into four time periods (referred to as

“Wake”, “Day”, “Evening”, and “Sleep”), and give each time period its own setpoint temperatures. Your “Heat Setpoint temperature” tells your heating system the room temperature to maintain during cold weather. The “Cool Setpoint

Temperature” tells your cooling system the room temperature to maintain during hot weather.

Factory Program: Your thermostat comes from the factory preprogrammed with all seven days of the week set to the times and temperatures shown in Table 15.

Fancoil Operation

Fancoil operation is either a 2-pipe or 4-pipe configuration which is determined by jumper selection JP4 (see Installing,

Mounting and Wiring the Thermostat‚ page 4).

Pipe Sensor Operation

A pipe sensor can be connected when the thermostat is configured for either 2-pipe or 4-pipe fan coil operation

(see JP4 jumper configuration). The Pipe sensor is used to determine the water temperature in the Main Coil. The Pipe

Sensor should be mounted on the Main Coil supply and wrapped with insulating material.

Pipe Sensor Input: 10K Remote Probe or a standard On-Off

Aqua-stat can be used for summer/winter changeover. ON

(closed) is winter heating mode and OFF (open) is summer cooling mode.

Purge Cycle Operation

With a pipe sensor connected, this thermostat will initiate a purge cycle if the sensed water temperature is ambiguous

(not adequately hot or cold). The purge cycle algorithm can be either temperature or time based, depending on the configuration of Service Menu 16.

IM 168-7 33

Appendix

Technical and Application Notes

Temperature-Based Purge

• When an Ambiguous mode is detected and a demand exists, a 3 minute purge timer begins and the Main

Output is opened.

• After the 3 minute purge cycle, the thermostat checks again to see if the water temperature is more than 15°F from set point, or above 80°F or below 60°F.

• If Winter or Summer mode is determined, normal

HVAC operation occurs. If still ambiguous, the thermostat checks to see if the COIL temperature is below 60°F or above 80°.

— Coil < 60°F = Summer Mode.

— Coil > 80°F = Winter mode.

• Purge Cycle is repeated until a non-ambiguous condition is sensed.

NOTE:

If at any time the demand goes away, the thermostat will abort the purge cycle.

Time-Based Purge (Default)

1. The time-based purge cycle will start a 3-min purge cycle and enable the Main Output if any of the following conditions occur: transition from OFF to

AUTO mode, Reset event, power cycle, and/or 1-hour timer expires.

2. After the 3 min purge cycle, a pipe sensor reading says:

Pipe is 15°F+ below the zone temp = Summer mode

Pipe is 15°F+ above the zone temp = Winter mode Pipe is within 15°F of zone temp = still Ambiguous 3 If a

Winter or Summer mode is determined, the appropriate heating/cooling occurs. The thermostat will purge and check pipe temperatures again after 1-hour.

If step 2 is still ambiguous, all thermostat outputs are disabled for 1 hour.

After 1 hour, the purge cycle resumes at step

HVACSetback Systems

Setback Operation - Remove JP3

This is a low level input that is normally open. When switch is closed, the T180 heating and cooling setback limits are used as temperature control points. Fan operation in setback is cycled with demand. Pressing any button will override setback for 1 hour. Setback will override any user setting unless control is turned to OFF.

Intelligent Occupancy Sensors like the SD200-001 and

SD200-002 can be used with this input to set the HVAC system to control at setback limits.

Door Switch Only Operation - Install JP3

A stand alone door or window switch can be connected to the T180 to disable the HVAC system (outputs) if a door or window is left open for more than 2 minutes. A one-time ten minute override can be initiated by pressing any thermostat key pad.

34 IM 168-7

Appendix

The T180 thermostat can be used with optional S200 series occupancy detection equipment. Purchasing and installing this equipment to compliment the thermostat adds energy savings by setting back HVAC operation during occupied and unoccupied times.

Occupancy Operation (Install JP3)

The T180 can be used with PECO S200 series occupancy detection equipment. The occupancy and switch inputs are designed to connect to the SB200 slave sensor and SE200 door switch.

The Occupancy Sensor is a low-level switch that is open when there is occupancy and closed when unoccupied.

The Door Switch is a low-level switch that is open when the door is open and closed when the door is closed. This system requires both an Occupancy Sensor and a Door Switch.

Operation From an Occupied Mode

The T180 operates normally and looks for a door close. A door close signal initiates occupancy status detection.

If occupancy is detected, the T180 will maintain normal

HVAC control. It then waits for a door open signal before determining occupancy again.

If no occupancy signal is detected within 2 minutes, the

T180 changes to unoccupied mode and controls at setback temperature values.

Operation From an Unoccupied Mode

In an Unoccupied State, the T180 sets heating and cooling set points to setback values, as determined in the service menu. In this mode, the fan is automatically set to cycle with demand.

The T180 will continually monitor the room for occupancy.

Any occupancy detection, including door open, will set the operation to occupied mode.

In either mode, if the door is left open for more than 2 minutes the T180 will disable the HVAC system. A onetime ten minutes override can be initiated by pressing any thermostat keypad.

Optional detection equipment configurations and operation are described below.


SB200-001 Occupancy Sensor

The SB200-001 occupancy sensor (Figure 11) serves as an occupancy sensor for automatic control of a guest room

HVAC system. It incorporates an innovative dual delay processor which allows the sensor to verify the nature of occupancies, and is capable of eliminating unnecessary actuations of the HVAC device due to unintentional passages or short time occupancies. The sensor may also serve as a slave sensor (Figure 12, page 15).

The sensor switch is open in occupied mode and closed in unoccupied mode. An optional door and/or window switch

(Figure 11) is open when the door/window is open and is closed when the door/window is closed.

NOTE:

To use this configuration, a jumper must be installed to JP3 to allow occupancy input.

NOTE:

An o ptional door and/or window switch (Figure 11) can be added for use with the SB200-001 sensor.

Operation

In an occupied mode, the thermostat operates normally and looks for a door open signal. When the door opens, the thermostat waits for a door close signal. If the door is open for more than two minutes, the thermostat turns the HVAC system outputs to OFF. During this two minute period, if any button is pressed on the keypad, the time delay is extended to ten minutes. The time delay can only be extended once. Once the HVAC outputs transition to OFF, a door closure is required to re-enable the outputs. When the door closes, the thermostat starts a two minute timer and tries to detect occupancy. If the timer expires and no occupancy is detected, the thermostat transitions to an unoccupied state.

If occupancy is detected while the timer is running, the thermostat will remain in the occupied mode.

In an unoccupied mode, the thermostat sets heating and cooling set points to setback values as determined by factory or user settings. The fan is automatically set to cycle with demand. The thermostat continually monitors the occupancy sensor and will enter into occupied mode if occupancy is detected.

If the installation is only using a door/window switch, the thermostat will disable the HVAC outputs if this output is open for longer than two minutes.

To enable door/window switch only operation, install a jumper to JP3 (see Installing, Mounting and Wiring the

Thermostat‚ page 4) and the occupancy input must be shorted to circuit common.

Optional equipment configuration #1 SD200-001 Occupancy Sensor

The SD200-001 occupancy sensor (Figure 12) serves as a master sensor for a guest room HVAC management system.

The sensor provides HVAC operation according to occupancy status, as well as door/window switch monitoring, selectable high/low temperature setback, form-C output, slave sensor connectivity, and a five minute door open HVAC shut-off.

NOTE:

To use this configuration, the jumper to JP3 is removed to allow setback input.

NOTE: An optional door and/or window switch (Figure 12) and slave sensor can be added for use with the

Operation

In an occupied mode, the SD200-001 occupancy sensor

(Figure 12) and door switch use advanced microprocessor logic to determine occupancy. A door open signal will initiate occupancy status detection. If the sensor determines that a room is occupied, it will allow normal HVAC control.

The sensor will wait for another door open signal before determining occupancy again.

In an unoccupied mode, the sensor continually monitors the room. Any occupancy detection will set the operation to occupied mode.

This system provides basic room setback and is ideal for control of HVAC in commercial spaces.

NOTE:

To use this configuration, the jumper to JP3 is removed to allow setback input.

Operation

With each occupancy detection, an OFF delay is started and can be set to delay for up to 30 minutes (Figure 13).

These thermostats are designed to control On-Off, N.O. and

N.C. valves, relays and Erie

®

three wire floating valves. These units may include a fan switch with one or more fan speed selections.

Mode Button Operation

OFF: All thermostat outputs are off, fan is still operational if connected to manual fan speed switch.

AUTO: The thermostat automatically selects heating or cooling mode depending on the set point and room temperature. The appropriate HEAT or COOL indicator is enabled in addition to AUTO. A 3°F dead-band is provided to prevent short cycling between heating and cooling modes.

After change-over the control points automatically shift so that the heating off-point or the cooling off-point equals the set point temperature.

COOL: The thermostat operates as a cooling-only thermostat. The heating outputs are disabled.

HEAT: The thermostat operates as a heating-only thermostat.

The cooling outputs are disabled.

If constructed without a mode button, the thermostat operates in Auto mode, subject to configuration of the 2/4 pipe jumper and pipe sensor input.

Fan Speed Switch Operation

Fan speed is determined by manual selection from fan switch

OFF to HIGH, MEDIUM and/ or LOW. In units with the

Cycling Fan Option (demand output), the Fan operation

(CYCLING vs. CONTINUOUS) is determined by application connections. In OFF position all outputs are off and display blank.

Up/ Down Arrow Operation

A first touch of either arrow will display the set point (a single set point is employed for both heating and cooling).

Continued pressure on either arrow will scroll the set point to new values. After three seconds with no pressure on either arrow, the selected set point becomes effective and the display of the room temperature resumes.

Setback Operation

Connection of the Setback Input to 24 VAC 1 will force the control into unoccupied mode (see wiring diagram). Pressing an arrow key or the mode button on the thermostat cover will disable the setback input for one hour.


If cold water is detected, the system will operate in summer mode and the Main output will be cooling. If hot water is detected, the system will operate in winter mode, the Main output will be heating and First Stage Secondary Output will be disabled. In the case of an ambiguous reading, neither hot nor cold, the thermostat will initiate a purge cycle.

OFF: All thermostat outputs are off, fan is still operational if connected to manual fan speed switch.

AUTO: The thermostat automatically selects heating or cooling mode depending on the set point and room temperature. The appropriate HEAT or COOL indicator is enabled in addition to AUTO. A 3°F dead-band is provided to prevent short cycling between heating and cooling modes.

After change-over the control points automatically shift so that the heating off-point or the cooling off-point equals the set point temperature.

COOL: The thermostat operates as a cooling-only thermostat. The heating outputs are disabled.

HEAT: The thermostat operates as a heating-only thermostat.


If constructed without a mode button, the thermostat operates in Auto mode, subject to configuration of the 2/4 pipe jumper and pipe sensor input.



OFF to HIGH, MEDIUM and/ or LOW. In units with the

Cycling Fan Option (demand output), the Fan operation

(CYCLING vs. CONTINUOUS) is determined by application connections. In OFF position all outputs are off and display blank.

Up/ Down Arrow Operation

A first touch of either arrow will display the set point (a single set point is employed for both heating and cooling).

Continued pressure on either arrow will scroll the set point to new values. After three seconds with no pressure on either arrow, the selected set point becomes effective and the display of the room temperature resumes.


Connection of the Setback Input to 24 VAC 1 will force the control into unoccupied mode (see wiring diagram). Pressing an arrow key or the mode button on the thermostat cover will disable the setback input for one hour.


If cold water is detected, the system will operate in summer mode and the Main output will be cooling. If hot water is detected, the system will operate in winter mode, the Main output will be heating and First Stage Secondary Output will be disabled. In the case of an ambiguous reading, neither hot nor cold, the thermostat will initiate a purge cycle.

Three Wire Floating Valve Operation

Open and Close outputs are used to position the valve. Stroke time is factory set at two minutes. Outputs are off after reaching full on or off position. Valves are periodically reset for accuracy.

Outside Air Damper Operation

This output is ON any time the control is turned ON.

44 IM 168-7


1. When no pipe sensor is used the main output controls cooling and the secondary output controls heating.

2. The pipe sensor should be mounted on the main coil input for water system operation and in the main duct system for forced air operation.

IM 168-7 53

Appendix

Fancoil Operation

Fancoil operation is either a 2-pipe or 4-pipe configuration which is determined by jumper selection JP4 (see “Mounting and Wiring the Thermostat”).

2-Pipe Operation

In this configuration, the thermostat permanently disables the secondary output and disables the fan from cycling in an invalid mode. The main output configuration is dependent on the pipe sensor input. With a pipe sensor connected, the thermostat automatically selects heating or cooling depending on the sensed water temperature. If the pipe sensor input is open (unconnected), the main output only cools. If the pipe sensor input is shorted, the main output only heats.

Normal thermostat default is for 4-pipe operation. For 2-pipe operation, install a jumper on JP4.

4-Pipe Operation

In this configuration, both the main output (COOL) and the secondary output (HEAT) are available. These both cycle

ON depending on the mode of the thermostat. With a pipe sensor connected, the thermostat automatically changes the main output to heat and disables the secondary output if the main coil water is hot. For 4-pipe operation, the JP4 jumper is removed.


A pipe sensor can be connected when the thermostat is configured for either 2-pipe or 4-pipe configuration. The pipe sensor is used to determine the water temperature in the main coil, which should be connected to the primary output.

Pipe sensor input—use a 10K Remote Probe or a standard

ON-Off Aquastat for summer/winter changeover.

Purge Cycle

With a pipe sensor connected, the thermostat initiates a purge cycle if the sensed water temperature is ambiguous

(not adequately hot or cold). The sequence for purge cycle operation is as follows:

1. The thermostat has a call for heat or cooling.

NOTE: If at any time the call goes away, the thermostat stops the purge cycle .

2.

The thermostat checks the pipe sensor to verify water temperature.

3. If the water temperature is beyond 15°F of the set point, normal HVAC control occurs.

4. If the water temperature is not beyond 15°F of the set point, the thermostat checks to see if the water temperature is above 80°F or below 60°F.

If yes, normal HVAC control occurs.

If no, the thermostat opens the main output (COOL) for three minutes.

5. After the three minute purge cycle occurs, the thermostat checks to see if the water temperature is more than 15°F from the set point, or above 80°F, or below 60°F.

If yes, normal HVAC operation occurs.

If no,

the valve is left open and the thermostat continues to search for a valid reading.

NOTE:

If at any time the demand goes away, the thermostat will stop the purge cycle .

In this configuration, the low level switch input normally is open. To enable setback operation, the JP3 jumper is removed

(see “Mounting and Wiring the Thermostat”). The input will close and the thermostat heating and cooling setback limits can then be used as temperature control points. Fan operation in setback is cycled with demand. Press any thermostat key to override setback for one hour. Setback overrides any user setting except if the control is turned to OFF.

Appendix


The T170 thermostat can be used with optional S200 series occupancy detection equipment. Purchasing and installing this equipment to compliment the thermostat adds energy savings by setting back HVAC operation during occupied and unoccupied times. Optional detection equipment configurations and operation are described below.

To enable door/window switch only operation, install a jumper to JP3 (see “Mounting and Wiring the Thermostat”) and the occupancy input must be shorted to circuit common.

Figure 10:


SB200-001 Occupancy Sensor

The SB200-001 occupancy sensor (Figure 10) serves as an occupancy sensor for automatic control of a guest room

HVAC system. It incorporates an innovative dual delay processor which allows the sensor to verify the nature of occupancies, and is capable of eliminating unnecessary actuations of the HVAC device due to unintentional passages or short time occupancies. The sensor may also serve as a slave sensor (Figure 11).

The sensor switch is open in occupied mode and closed in unoccupied mode. An optional door and/or window switch

(Figure 10) is open when the door/window is open and is closed when the door/window is closed.

NOTE:

To use this configuration, a jumper must be installed to JP3 to allow occupancy input .

NOTE:

An optional door and/or window switch (Figure 10) can be added for use with the SB200-001 sensor .

Operation

In an occupied mode, the thermostat operates normally and looks for a door open signal. When the door opens, the thermostat waits for a door close signal. If the door is open for more than two minutes, the thermostat turns the HVAC system outputs to OFF. During this two minute period, if any button is pressed on the keypad, the time delay is extended to ten minutes. The time delay can only be extended once. Once the HVAC outputs transition to OFF, a door closure is required to re-enable the outputs. When the door closes, the thermostat starts a two minute timer and tries to detect occupancy. If the timer expires and no occupancy is detected, the thermostat transitions to an unoccupied state.

If occupancy is detected while the timer is running, the thermostat will remain in the occupied mode.

In an unoccupied mode, the thermostat sets heating and cooling set points to setback values as determined by factory or user settings. The fan is automatically set to cycle with demand. The thermostat continually monitors the occupancy sensor and will enter into occupied mode if occupancy is detected.

If the installation is only using a door/window switch, the thermostat will disable the HVAC outputs if this output is open for longer than two minutes.


The SD200-001 occupancy sensor (Figure 11) serves as a master sensor for a guest room HVAC management system.

The sensor provides HVAC operation according to occupancy status, as well as door/window switch monitoring, selectable high/low temperature setback, form-C output, slave sensor connectivity, and a five minute door open HVAC shut-off.

NOTE:

To use this configuration, the jumper to JP3 is removed to allow setback input .

NOTE: An optional door and/or window switch (Figure 11) and slave sensor can be added for use with the

SD200-001 sensor .

Operation

In an occupied mode, the SD200-001 occupancy sensor

(Figure 11) and door switch use advanced microprocessor logic to determine occupancy. A door open signal will initiate occupancy status detection. If the sensor determines that a room is occupied, it will allow normal HVAC control.

The sensor will wait for another door open signal before determining occupancy again.

In an unoccupied mode, the sensor continually monitors the room. Any occupancy detection will set the operation to occupied mode.

Operation

With each occupancy detection, an OFF delay is started and can be set to delay for up to 30 minutes.

The SD200-002 occupancy sensor serves as a stand alone master sensor for a guest room HVAC management system.

The sensor provides HVAC operation according to occupancy status, as well as selectable high/low temperature setback, form-C output, and a five minute door open HVAC shut-off.

This system provides basic room setback and is ideal for control of HVAC in commercial spaces.

NOTE:

To use this configuration, the jumper to JP3 is removed to allow setback input .
