Overview

Controller Overview

General

The HB Controller is designed to work with a normal 24 VAC Thermostat and Dehumidistat. Single or Multi-stage Thermostats can be used. When a Single-Stage Thermostat is used, an auto-staging feature is built-in for

Multi-stage HB units. Fan speed can be adjusted for both high and low speeds by way of an interface when the HB unit is equipped with an adjustable speed controller. Dehumidifi cation is optimized by use of a

Return Air Bypass damper. Modulating Hot-Gas Reheat can be used to reheat the Supply Air during Dehumidifi cation.

sensor can be connected through the wiring harness when IAQ control is desired. Also, two damper positions are available when using

Two-Speed Supply Fans, thus providing enhanced IAQ control.

Outputs

The HB Controller also monitors equipment safeties, logs information, and locks out the equipment in the event of multiple failures. All sensors are needed in order to provide all modes of operation. However, to prevent a potential freeze condition, Heating Mode will still operate if all sensors have failed or are missing.

Terminal block style connections are provided for fi eld wiring of the

Thermostat, Dehumidistat, and Supply Air Temperature Sensor wires.

All other inputs and outputs are connected via a wiring harness on the

HB unit. A list of all available inputs and outputs follows.

Sequence of Operations

Controller Sequence of Operations

Fan Mode

The HB Controller supports 2 different Supply Fan confi gurations. It can be confi gured for Adjustable Two-Speed Fan or Two-Speed Fan. On a call for “G,” the Supply Fan runs at Low Speed. Minimum on and off times are maintained in the event of a short cycled call for “G.”

Heating Mode

On a call for “W1,” the Supply Fan runs at High Speed (maintained during the Heating mode), and Heat Stage 1 is energized. On a call for

“W2,” Heat Stage 2 is energized after the Stage-Up delay. If “W2” is called without “W1,” Heat Stage 1 is energized, and then Heat Stage 2 is energized after the Auto Stage-Up Delay period. On a call for “W3,”

Heat Stage 3 is energized after the Stage-Up delay. If “W3” is called without “W1” or “W2,” Heat Stages 1, 2, and 3 will energize based on

Auto Stage-Up Delays.

Auto Stage-Up Delay Expires or a call for “Y2” is made. When “Y2” is called, Cool Stage 2 will activate after the Cooling Auto Stage-Up

Delay. After Cool Stage 2 is activated, the Supply Fan will switch to

High-Speed operation.

Economizer IAQ Control

The economizer is also used for CO

2 the Minimum CO

2

control. If the CO

2

level is above

PPM setpoint, the Economizer Minimum Position will be reset proportionally between the Minimum CO

2

PPM and Maximum

CO

2

PPM setpoints. When the CO

2 level is above the Maximum CO

2

PPM setpoint, the Economizer will open as far as the Maximum Damper

Adjustment Position setpoint setting. There are two Minimum and two

Maximum Economizer Damper Positions depending on the Supply Fan speed. These are the Maximum Damper Position with Low-Speed Fan, the Minimum Damper Position with Low-Speed Fan, the Maximum

Damper Position with High-Speed Fan, and the Minimum Damper Position with High-Speed Fan. The air balancing contractor should determine these settings in order to maintain the proper amount of fresh air being supplied to the building.

Cooling Mode

If the HB Controller is confi gured for 1 stage of Cooling, on a call for

“Y1,” the Supply Fan runs at High speed, and Cool Stage 1 will energize.

If the HB Controller is confi gured for 2 stages of Cooling, on a call for

“Y1,” the Supply Fan runs at Low Speed, and Cool Stage 1 is energized.

On a call for “Y2,” the Supply Fan runs at High Speed, and Cool Stage

2 is energized after the Stage-Up Delay. If “Y2” is called without “Y1,”

Cool Stage 1 is energized, and then Cool Stage 2 is energized after the

Auto Stage-Up Delay.

Economizer Cooling

General Economizer Operation

If the Outdoor Air Temperature is below the Economizer Enable Setpoint and there is a call on “Y1,” the compressors will be locked out, and the

Economizer will modulate to achieve a 55° F Supply Air Temperature.

If the HB Controller is confi gured for 1 stage of Cooling, on a call for

“Y1,” the Supply Fan will run at High Speed. If the HB Controller is confi gured for 2 stages of Cooling, on a call for “Y1,” the Supply Fan will run at low speed. When “Y2” is called, the Supply Fan will go to high speed.

Economizer Operation with ECS Control

If the Enthalpy Changeover Switch (ECS) is closed and the outdoor air temperature is below the ECS, OAT Enable setpoint (default 65° F), the economizer will modulate and attempt to achieve 55° F supply air temperature. If the outdoor air temperature is above 55° F, the economizer will generally open to 100%. Mechanical cooling can be used to supplement the economizer if the outdoor air temperature is above the ECS OAT Enable setpoint and the economizer signal is at 100%.

Once mechanical cooling is activated to supplement the economizer, the economizer will remain at 100% until the cooling call is satisfi ed.

Mechanical Cooling Staging with ECS Control

If the HB Controller is confi gured for 1 stage of Cooling, on a call for

“Y1,” the Supply Fan will run at High Speed. Cool Stage 1 will activate after the Cooling Auto Stage-Up Delay. If the HB Controller is confi gured for 2 stages of Cooling, on a call for “Y1,” the Supply Fan will run at Low Speed. Cool Stage 1 will activate after either the Cooling

Economizer Dehumidifi cation

1-or 2-Stage Cooling Units with Adjustable

Two-Speed or Two-Speed Supply Fan Control

If the Outdoor Air Temperature is below the Economizer Enable Setpoint and there is a call for Dehumidifi cation on “RH,” the compressors will be locked out, and the Economizer will modulate to achieve 55° F Supply Air Temperature. The Supply Fan will run at Low Speed, and the

Return Air Bypass will be closed.

For 1 stage Cooling units, on a call for “Y1,” the HB Controller will enter the Cooling Mode, and the Supply Fan will run at High Speed. The

Cooling Mode will be maintained until “Y1” is satisfi ed. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume.

For 2 stage Cooling Units, “Y1” is ignored during this mode to extend

Dehumidifi cation. On a call for “Y2,” the HB Controller will enter the

Cooling mode, and the Supply Fan will run at High Speed. The Cooling

Mode will be maintained until both “Y2” and “Y1” are satisfi ed. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume, and the Supply Fan will run at Low Speed.

If the HB Controller is confi gured for 1 stage of Heating, on a call for

“W1,” the mode changes to Heating. The Economizer will close to its

Minimum Position, Heat Stage 1 will energize, and the Supply Fan will run at High Speed.

If the HB Controller is confi gured for 2 or 3 stages of Heating, on a call for “W1,” the Economizer will be locked at its current position, attempting to deliver 55° F Supply Air to the heating section. Heat Stage 1 is energized, and the Supply Fan will run on High speed. On a call for “W2,” the HB Controller will enter the Heating Mode. The Economizer will move to its Minimum Position, and Heat Stage 2 will energize after the

Stage-Up Delay. The Heating Mode will be maintained until both “W2” and “W1” are satisfi ed. W3 is also available for 3 Stage Electric Heating

Units. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume, and the Supply Fan will run at Low Speed.

2-Stage Cooling with Adjustable Two-Speed or

Two-Speed Supply Fan Control

On a call for “RH,” Cool Stage 1 is energized, and the Supply Fan runs at low speed. The Return Air Bypass is opened to 100%. The hot-gas reheat will then modulate the valves to achieve the Supply Air setpoint

DIP switch setting. On a call for “Y1,” the Supply Air setpoint on the reheat controller is lowered 10° F, and the Return Air Bypass will close.

On a call for “Y2,” the HB Controller will enter the Cooling Mode. The

Supply Fan will switch to high speed, and Cool Stage 2 is energized. The modulating hot-gas reheat valves will move to the full Cooling position.

The Cooling mode will be maintained until both “Y2” and “Y1” are satisfi ed. As long as there is still a call for “RH,” the dehumidifi cation mode will resume.

If the HB Controller is confi gured for 1 stage of Heating, on a call for

“W1,” the mode changes to Heating. Cool Stage 1 will de-energize, the

Return Air Bypass will close, Heat Stage 1 will energize, and the Supply

Fan will run at High Speed.

If the HB Controller is confi gured for 2 or 3 stages of Heating, a “W1” call will be delayed to extend Dehumidifi cation. On a call for “W2,” the HB Controller will enter the Heating Mode. Cool Stage 1 will deenergize, the Return Air Bypass will close, Heat Stage 1 will energize, and the Supply Fan will run at High Speed. Heat Stage 2 will energize after the Auto Stage-Up Delay. The Heating Mode will be maintained until both “W2” and “W1” are satisfi ed. W3 is also available for 3-

Stage Electric Heating Units. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume, and the Supply Fan will run at Low Speed.

“W1,” the mode changes to Heating, and the Supply Fan will run at High

Speed. Cool Stage 1 will de-energize, the Return Air Bypass will close,

Heat Stage 1 will energize, and the Supply Fan will run at High Speed.

If the HB Controller is confi gured for 2 or 3 stages of Heating, on a call for “W1,” the Supply Air Setpoint on the Reheat Controller is raised

10° F, and Cool Stage 1 continues to run. On a call for “W2,” the HB

Controller will enter the Heating Mode. Cool Stage 1 will de-energize, the Return Air Bypass will close, Heat Stage 1 will energize, and the

Supply Fan will run at High Speed. Heat Stage 2 will energize after the

Auto Stage-Up Delay. The Heating Mode will be maintained until both

“W2” and “W1” are satisfi ed. W3 is also available for 3 Stage Electric

Heating Units. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume, and the Supply Fan will run at Low Speed.

Lockout Modes

Dehumidifi cation Mode with Hot-Gas

Reheat

1-Stage Cooling with Adjustable Two-Speed or Two-Speed Supply Fan Control

On a call for “RH,” Cool Stage 1 is energized, and the Supply Fan runs at High Speed. The Return Air Bypass is opened to 100%. The

Hot Gas Reheat will then modulate the valves to achieve the Supply

Air Setpoint DIP Switch setting. On a call for “Y1,” the HB Controller enters the Cooling Mode. The Return Air Bypass will close, and the

Hot Gas Reheat will modulate to full Cooling. The Cooling Mode will be maintained until “Y1” is satisfi ed. As long as there is still a call for

“RH,” the Dehumidifi cation Mode will resume.

Heating Mode is locked out if the HSM (Heat Safety Monitor) trips 3 times during a call for Heating. To reset the lockout condition, either remove the call for Heating or cycle power to the HB Controller. Heating Mode is also locked out if the Outdoor Air Temperature is above the

OAT Heat Lockout setpoint temperature.

Cooling Mode is locked out if the LPS (Low Pressure Switch) trips 3 times during a call for Cooling or Dehumidifi cation. To reset the lockout condition, either remove the call for Cooling or Dehumidifi cation or cycle power to the HB Controller. Cooling Mode is also locked out if the Outdoor Air Temperature is below the OAT Cool Lockout setpoint temperature or if the OAT Sensor is bad or missing.

If the HB Controller is confi gured for 1 stage of Heating, on a call for

“W1,” the mode changes to Heating, and the Supply Fan will run at

High Speed. Cool Stage 1 will de-energize, the Return Air Bypass will close, Heat Stage 1 will energize, and the Supply Fan will run at High

Speed. If the HB Controller is confi gured for 2 or 3 Stages of Heating, on a call for “W1,” the Supply Air Setpoint on the Reheat Controller is raised 10° F, and Cool Stage 1 continues to run. On a call for “W2,” the HB Controller will enter the Heating Mode. Cool Stage 1 will deenergize, the Return Air Bypass will close, Heat Stage 1 will energize, and the Supply Fan will run at High Speed. Heat Stage 2 will energize after the Auto Stage-Up Delay. The Heating Mode will be maintained until both “W2” and “W1” are satisfi ed. W3 is also available for 3-

Stage Electric Heating Units. As long as there is still a call for “RH,” the Dehumidifi cation Mode will resume.

Sequence of Operations

Controller Sequence of Operations

SAT Lockout Modes

Note: The SAT Lockout Modes only apply if a Supply Air

Temperature Sensor is installed on the HB unit.

SAT High Temperature Limit Cut Off Mode

During the Heating Mode, if the Supply Air Temperature rises above the Supply Air High Temperature Limit Cut Off (150° F), the Heating will stage off, but the main Supply Fan will remain on in Low-Speed operation. If this occurs, the Supply Air Temperature must fall below

80° F in order for the Heating to stage back on. If this condition occurs 2 times consecutively during a Heating call, the HB Controller will lockout in Supply Air High Temperature Limit Cut Off. To restore normal operation, either remove the call for Heating or cycle power to the HB Controller.

Exhaust Fan Control

The Exhaust Fan is energized via the Auxiliary Relay. The Exhaust Fan has two Economizer Position Activation points based on the Low- and

High-Speed Supply Fan condition. The air balancing contractor should determine these settings for proper Building Pressure Control.

HB Processor Board

When the HB Controller has the optional HB Processor board installed, a Space Temperature Sensor can be connected to it for HVAC Mode

Control. When the Space Temperature Sensor is used, the Push-Button

Override and Slide Adjust options are also available. Occupied and

Unoccupied Modes are available through week scheduling, force schedule, and a broadcast schedule. The HB Processor board also provides communication with other HB controllers. Up to 60 other controllers can be connected together via the RS-485 loop.

Space Temperature Control Sequence

When the Space Temperature Sensor is confi gured for control, Cooling and Heating setpoints are used to activate the HVAC Modes of operation.

An HVAC Mode Deadband setpoint is used to determine the temperature at which the Cooling and Heating Modes are activated above or below the setpoints. Once in the Cooling Mode, the Space Temperature must drop below the Cooling setpoint minus the deadband to enter the Vent Mode.

The same is true for the Heating mode; the Space Temperature must rise above the Heating setpoint plus the deadband to enter the Vent Mode.

An additional Cooling Stage is activated for each 1° F rise of the Space

Temperature above the Cooling Setpoint up to the maximum number of

Cooling Stages available. In like manner, an additional Heating Stage is activated for each 1° F drop of the Space Temperature below the Heating

Setpoint up to the maximum number of Heating Stages available.

SAT Low Temperature Limit Cut Off Mode

During the Heating Mode, if the Supply Air Temperature falls below the Supply Air Low Temperature Limit Cut Off (40° F), the Outdoor

Air Damper will close. If the Supply Air Temperature is still too cold and remains there for 15 minutes, the Heating and the Supply Fan will be turned off and locked out. This condition can only happen once, and then the HB Controller will lockout in Supply Air Low Temperature

Limit Cut Off. To restore normal operation, either remove the call for

Heating or cycle power to the HB Controller.

When the Space Temperature rises above the Cooling setpoint plus the deadband, the HB Controller enters the Cooling Mode, and Cooling Stage

1 is activated. Cooling Stage 2 is activated if the Space Temperature rises by another 1° F above the Cooling setpoint. Cooling Stage 2 deactivates when the Space Temperature drops below the Cooling setpoint. Cooling Stage 1 deactivates when the Space Temperature drops below the

Cooling setpoint minus the deadband.

When the Space Temperature drops below the Heating setpoint minus the deadband, the HB Controller enters the Heating Mode, and Heating

Stage 1 is activated. Heating Stage 2 is activated if the Space Temperature drops by 1° F. Heating Stage 3 is activated if the Space Temperature drops by another 1° F below the Heating setpoint. Heating Stage 3 and

Heating Stage 2 both deactivate when the Space Temperature rises above the Heating setpoint. Heating Stage 1 deactivates when the Space

Temperature rises above the Heating setpoint plus the deadband.

The Slide Adjust feature on the Space Temperature Sensors that are equipped with this option allows the user to change the Heating and

Cooling setpoints up or down by the Slide Adjust setpoint value. If 3°

F is entered as the Slide Adjust setpoint, when the slider is all the way up, the Heating and Cooling setpoints will be raised by 3° F. When the slider is all the way down, the Heating and Cooling setpoints will be lowered by 3° F. The Override Button feature on Space Temperature sensors that are equipped with this option allows the user to force the

HB Controller into the Occupied Mode. The time the controller is in

Occupied Mode is determined by the Override Time Setpoint. Once this time is expired, the HB Controller will follow its normal schedule.

A momentary push of the Override Button will activate the Override.

Once in the Override Mode, pushing down and holding the Override

Button for 5 seconds will deactivate the Override Mode.

HB Controller Technical Guide

Installation & Wiring

Controller Installation & Wiring

Controller Mounting

It is important to mount the controller in a location that is free from extreme high or low temperatures, moisture, dust, and dirt. Be careful not to damage the electronic components when mounting the controller.

The HB controller mounts in the HB unit control panel using the 4 plastic standoffs located on the HB control enclosure mounting base.

Important Wiring Considerations

Please carefully read and apply the following information when wiring the HB controller.

1. All 24 VAC wiring must be connected so that all ground wires remain common. Failure to follow this procedure can result in damage to the controller and connected

devices.

2. All wiring is to be in accordance with local and national electrical codes and specifi cations.

3. Minimum wire size for 24 VAC thermostat wiring should be 22 gauge.

4. Minimum wire size for all sensors should be 24 gauge.

5. Be sure that all wiring connections are properly inserted and tightened into the terminal blocks. Do not allow wire strands to stick out and touch adjoining terminals which could potentially cause a short circuit.

6. Be sure all modular wiring harness connectors are seated fi rmly in their respective modular connectors on the HB

Supply Air Temperature

You can set the desired Discharge Air Temperature Setpoint using the

DIP Switch labeled SETPOINT on the MHGRV Module. See Figure 9 for location and DIP Switch setting instructions. The MHGRV Module will allow you to set a Supply Air Temperature Setpoint between 50° F and 100° F. If a value of less than 50° F is set, the controller will default to a 50° F Supply Air Temperature Setpoint. A value greater than 100°

F will cause the unit to default to a 100° F Supply Air Temperature

Setpoint.

Example:

We want the Discharge Air Temperature Setpoint to increase from 55° F when the Reset Input signal is at 0 Volts to 75° F when the Reset Input signal is at 10 Volts.

•

Set the SETPOINT DIP Switch to 55° F

•

Set the RESET LIMIT DIP Switch to 75° F

The discharge air temperature will now increase from 55° F to 75° F as the Reset Input voltage signal ramps from 0 Volts to 10 Volts.

Supply Air Temperature Reset Limit

You can reset the Supply Air Temperature Setpoint by supplying a 0-10

VDC control signal to the Reset Input (MHGRV RESET) terminal on the HB controller board. The reset range is determined by the setting confi gured on the DIP Switch labeled “RESET LIMIT.” See Figure 9 for location and setting instructions. The controller will reset the Supply Air Temperature Setpoint from the value set on the SETPOINT DIP

Switch to the value set on the RESET LIMIT DIP Switch as the Reset

Input (RST IN) signal is increased from 0 Volts to 10 Volts.

Note: It is possible to create a “reverse acting” control sequence.

Using the temperatures from the example above by setting the SETPOINT DIP Switch to 75

° F and the RESET

LIMIT DIP Switch to 55

° F, the reset would be reverse acting. In this case, the controller will maintain a 75

° F discharge temperature when the Reset Input signal is at

0 Volts and will reduce to 55

° F when the Reset Input signal is at 10 Volts.

MHGRV Module Settings

Optional MHGRV Module Settings

When a change is made to the DIP Switch settings for either the setpoint or reset, power does not have to be cycled in order for the controller to read their values. The DIP Switch settings and their corresponding setpoints can be changed while power is applied, and the new settings will be accepted. The same is true for entering or leaving the force mode

DIP Switch settings.

The modulating reheat system on the HB Unit is comprised of two valves, one for the condenser coil and one for the reheat coil. The valves operate directly opposite of each other. The MHGRV Controller will move the valves to the full Cooling position on power up after valve calibration. The condenser valve will be fully opened, and the reheat valve will be fully closed. This is the default confi guration when no reheat is required.

For fi eld-testing purposes, the modulating hot-gas valves can be forced to full Cooling or full Reheat via DIP Switch settings on the MHGRV

Controller. See Table 1 for mode of operation and valve position during force modes.

Table 14, continued: Temperature Sensor - Voltage

& Resistance for Type III Sensors

Thermistor Sensor Testing Instructions

1.) Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered).

2.) Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts. Place the “-” (minus) lead on GND terminal and the “+” (plus) lead on the sensor input terminal being investigated.

If the voltage is above 3.3 VDC, the sensor or wiring is “open.” If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
