SETTINGS

Using Thermostat Keys

The thermostat keys are used to:

• set current time and day,

• program times and setpoints for heating and cooling,

• override the program temperatures,

• display present setting,

• set system and fan operation,

• configure Installer Setup,

• check Installer System Test.

See Fig. 11 for key information.

Setting System and Fan (select models)

The system default setting is Heat. The fan default is set so the fan operates continuously in Occupied periods,

Unoccupied period recovery times and with the heating and cooling equipment in Unoccupied periods. Use the System and Fan keys to change the settings. Fan and system operation are configured in the Installer Setup options.

The system settings are:

Em Heat (T7200E, T7300/Q7300C,D): Emergency heat relay is on continuously. Thermostat cycles highest stage of heat. Cooling system is off. Compressor is de-energized.

Heat: Thermostat controls the heating.

Off: Both the heating and cooling are off.

Cool: Thermostat controls the cooling.

Auto: Thermostat automatically changes between heating and cooling depending on the indoor temperature.

The fan settings are:

On: Fan operates continuously in occupied period.

Auto: Equipment controls the fan in the Unoccupied periods. The Intelligent Fan™ operation (Installer Setup number 17) offers three choices for the fan operation in

Occupied periods:

— fan turns on only when there is a call for heating or cooling.

— fan operates continuously in Occupied periods.

— fan is on continuously in Occupied periods and

Unoccupied period recovery times.

Setting Temperature

Refer to Table 7 for the default temperature setpoints. See

Programming section for complete instructions on changing the setpoints.

PROGRAMMING

The keyboard is located behind the thermostat cover. Up to sixteen keys are used to set, review and modify programmed times and temperature settings. The thermostat display shows day, time, program period and temperature.

The thermostat can be set for two Occupied and two

Unoccupied times for each day of the week (28 independent time settings). Temporary Occupied key provides quick temporary temperature changes for increased occupant comfort. The Continuous Unoccupied key provides energy efficient operation for extended periods of time.

IMPORTANT

To program the thermostat, 24 Vac is required (turn on system power). The keyboard lockout feature must be disabled by setting the DIP switch 1 on the back of the thermostat to the Off position.

Before starting the program procedure, use Table 11 to organize the program schedule.

OPERATION

T7200/T7300 Relay Logic

The T7200/T7300 contains three switching relays. In conventional applications, the relays control first stage cooling, first stage heating, and fan. In heat pump applications, the relays control the heat pump compressor, auxiliary heat, and the fan. Because of this change in switching logic, it is important to use Q7300C,D Subbases when the T7300 is set for heat pump applications and the Q7300A,G Subbases when the T7300 is set for conventional applications.

The T7200D Relay Logic is for conventional applications. The

T7200E Relay Logic is for heat pump applications.

T7200/T7300 and Conventional Thermostats

P+I Control

The T7200/T7300 microprocessor based control requires that the user understands temperature control and thermostat performance. A conventional electromechanical or electronic thermostat does not control temperature precisely at setpoint.

Typically, there is an offset (droop) in the control point as the system load changes. This is a phenomenon that most people in the industry know and accept. Many factors contribute to offset including switch differential, thermal lag, overshoot, cycle rates and system load.

The thermostat microprocessor simultaneously gathers, compares and computes data. Using this data, it controls a wide variety of functions. The special proprietary algorithm

(program) in the thermostat eliminates the factors causing

T7200D,E, T7300D,E,F AND Q7300 SERIES 2000 PROGRAMMABLE COMMERCIAL THERMOSTATS AND SUBBASES offset. This makes temperature control more accurate than the conventional electromechanical or electronic thermostats.

The temperature control algorithm is called proportional plus integral (P+I) control.

The thermostat sensor, located on the thermostat or remote, senses the current space temperature. The proportional error is calculated by comparing the sensed temperature to the programmed setpoint. The deviation from the setpoint is the proportional error.

The thermostat also determines integral error, which is a deviation based on the length of error time. The sum of the two errors is the (P+I) error. The cycle rate used to reach and maintain the setpoint temperature is computed using the P+I.

The addition of the integral error is what differentiates the thermostat from many other electronic and electromechanical thermostats. See Fig. 17.

T7200/T7300 Thermostat Operation

Startup

When power to the thermostat is turned on, a startup and initialization program begins. The startup occurs only on initial powerup. After total loss of power for an extended period, the current time and day may need to be set, but the user program is held. The initial default values are heating 68

°

F

(20

°

C) and cooling 78

°

F (26

°

C) for the Occupied periods.

Unoccupied default values are heating 55

°

F (13

°

C) and cooling 90

°

F (32

°

C).

NOTE: The thermostat controls to the Unoccupied default setpoints of 55

°

F (13

°

C) for heat and 90

°

F (32

°

C) for cool when no program is set.

Occupied Operation

When the thermostat is operating in the Occupied period, the temperature is controlled to the occupied heat or cool setpoint. The normally open (A1 ) auxiliary relay contacts are closed and the normally closed (A3) auxiliary relay contacts are opened during the Occupied periods (if the subbase being used has this option). The fan operates as follows: fan selection can be set to On (always energized) or Auto (cycles with Y1 or W1).

Unoccupied Operation

When the thermostat is operating in the Unoccupied period, the temperature is controlled to the Unoccupied heat or cool setpoint. The normally open (A1) relay contact is open and the normally closed (A3) relay contact is closed. The fan operates as follows: fan is always intermittent (cycles with Y1 or W1).

Equipment Protection

As part of the operational sequence, the T7200/T7300 microprocessor also incorporates minimum on and off times for all heating and cooling stages. Minimum on time is set in

Intelligent Recovery® Feature

Intelligent Recovery® feature is a Honeywell trademark for the way the thermostat controls the heating and cooling equipment during recovery from Unoccupied to Occupied setting. During recovery, the control point changes gradually rather than jumping from the energy saving setting to the comfort setting all at once.

When the Intelligent Recovery® feature is used in heating, the control point raises gradually, maximizing the use of the more economical first stage heat to bring the sensed temperature to the desired comfort setpoint. This minimizes using the typically more expensive second-stage heat.

The advantages are:

• Comfort setting is achieved at the programmed time and maintained regardless of weather conditions; occupants are comfortable.

• Drafts from low temperature discharge air are minimized during occupied periods.

• Thermostat automatically uses the more economical first stage of heat as the primary heat source during recovery, avoiding the use of the expensive second stage heating.

• Comfort and energy savings can be achieved in both heating and cooling.

• The thermostat reduces heat cycling, extending equipment life.

Recovery from Unoccupied

The heating heat pump recovery ramp is 3

°

F per hour, which differs from the 5

°

F per hour for conventional systems. The

3

°

F helps the system use the economical heat pump more and the expensive auxiliary heat less. The cooling ramp is

5

°

F, the same as for conventional systems.

Conventional System

The T7200 and T7300D,F Thermostats with Q7300A,G

Subbases are designed for conventional heat/cool applications.

Heat Pump Operation

The T7200E and T7300E,F Thermostats with Q7300C,D

Subbases are used for heat pump applications. Additional information is required when configured for heat pump applications.

O and B Terminals for Heating or Cooling Changeover

The Q7300C controls heat pump changeover. The Q7300D is only used in a heat pump application when the heat pump controls the reversing valve changeover. See Table 13 for the operation of the O and B terminals on the Q7300C.

O and B Terminals on a Conventional Subbase

Conventional subbase O and B terminals can be used to drive dampers and valves. The O terminal is energized on a call for cooling and the B terminal is energized on a call for heating.

When the system is calling for cool or is de-energized, but c the last function was cool.

When the last function was heating, the operation is the same as Auto (Heat). If the last function was cooling, the operation is the same as Auto (Cool).

Fan Operation

When the fan is set to On, the fan is energized continuously in the Occupied period. The Auto setting energizes the fan with the heating or cooling system. If the subbase is Q7300D, the fan cycles with Y1 and W1 during Unoccupied period.

Emergency Heat

When the system is set for Em Heat (on select T7300

Thermostats), the auxiliary heat is stage one and the compressor stages are locked off. The fan cycles with the auxiliary heat.

GENERAL OPERATION INFORMATION

Cycle Rates

The thermostat control algorithm maintains the temperature by cycling stages of heating or cooling to meet setpoint.

Subbase Auxiliary Relay

The Q7300 Auxiliary Relay output acts as a time-of-day switch to be used with an economizer minimum position control. The normally open (A1) auxiliary relay contacts are closed during the Occupied period and open during the

Unoccupied period. The normally closed (A3) auxiliary relay contacts are open during the Occupied period and closed during the Unoccupied period. The contacts are in the normal state during recovery.

Interfacing with

Electromechanical Economizers

(Subbases with Auxiliary Relay)

Mechanical cooling is often used when outside temperatures are in the 50

°

to 60

°

F range and humidity is below 50 percent. In central and northern climates, hundreds of hours fall into this temperature category. By permitting 80 to 100 percent outside air into the system, mechanical cooling may not be needed at all, particularly during Spring and Fall.

An economizer is used to take advantage of the outside air.

The typical economizer consists of an outside air damper, motor, outdoor air changeover control and a minimum position potentiometer. The motor controls the dampers.

Suitability of the outside air for cooling is determined by the outdoor air changeover control. The potentiometer is used for adjusting the minimum position of the economizer dampers, which provide a minimum amount of fresh air for ventilation.

The economizer reduces compressor run time, thereby saving energy and extending the compressor life. The drawback to using the economizer is that during the Unoccupied period, if there is no call for cooling or outdoor air is not suitable for free cooling, the economizer is controlled to minimum position. This position allows some percentage of outdoor air to enter the building, regardless of air suitability. The situation can cause the heating or cooling to run more often than if suitable outdoor air is permitted to enter the building.

The thermostat can take advantage of an economizer by connecting the auxiliary relay contacts (A1 and A2) of the subbase to control the economizer minimum position potentiometer. The contacts close during the Occupied period, allowing the economizer to operate normally. The contacts are open during the Unoccupied period, disabling the minimum position feature of the economizer. The open contacts cause the economizer to drive dampers fully closed instead of staying at minimum open position. This reduces the possibility of unsuitable outdoor air from entering the building, which lowers the internal load on the HVAC system and saves additional energy.

Other Uses for the Auxiliary Relay

Examples of other uses of the auxiliary relay are hot water heaters, lighting or baseboard heat. The additional loads are connected to the auxiliary relay contacts on the subbase. The contacts are rated for 1.6A at 30 Vac, but can be adapted to higher current applications with the use of an external relay and transformer. See Fig. 18.
