IMPORTANT

or remote-mounted sensor.

To avoid electrical interference, which can cause erratic performances, keep wiring runs as short as possible and do not run thermostat wires a dja ce nt to the line voltage electrical distribution systems. Use shielded cable (Belden type 8762 or equivalent for 2-wire and Belden type 8772 or equivalent for 3-wire). The cable shield must be grounded only at the controlled equipment case.

Q7300 Subbase with Remote-Mounted Temperature Sensor(s)

If only the remote-mounted temperature sensor(s) is used to sense and control room temperature, then install the thermostat in an area that is accessible for setting and adjusting the temperature and settings.

If both the subbase and remote-mounted temperature sensor(s) are used to sense and control room temperature, then install the subbase about 5 ft above the floor in an area with good air circulation.

Install the remote-mounted sensor(s) about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. See Fig. 2.

If multiple remote sensors are required, they must be arranged in a temperature averaging network consisting of two, three, four, five or nine sensors. See Fig. 3 through 8.

NOTES:

— When sensor averaging, the T7147A can be substituted

— Up to four T7147As can be used in parallel to place the

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 a Q7300C,D, Q7300H2003, or Q7300H2011 Subbase when the T7300 is set for heat pump applications and a Q7300A,G, Q7300H2029 Subbase 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 Thermo stats

P+I Control

The T7200/T7300 micro processo r based con trol requires that the user understands temperature control and thermostat performance. A conventional electromechanical or electronic thermostat does not co ntro l temperature precisely at s etpoint. Typically, there is an offset (droop) in the control point as the system load chang es. This is a phen omenon th at most p eople in the industry know and accept. Many factors contribute to offset including switch differential, th ermal lag, ov ershoot,

After total loss of power for an extended peri od , 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).

This makes temperature control more accurate than the conventional electromechanical or elec tro nic the rmo stats. 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 t o the programmed setpoint. The deviation from the setpoint is the

Occupied Operation

When the thermostat is operating in the Occu pi ed peri od, 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 Occu pied period s (if the subba se being used has this option). The fan operates as follows: fan selection can be set to On (alway s energized) or Auto (cycles with Y1 or W1).

proportional error.

Unoccupied Operation

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 el ec tron ic and elec tro me cha ni cal thermostats. See Fig. 18.

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 the installer setup number 32. Using the minimum on and off times assures that rapid cycling of equipment does not occur, which extends equipment life. Minimum on and off times are set in the Installer Setup.

63-4355—420

When the thermostat is operating in the Unoccu pie d perio d, the temperature is controlled to the Unoccupied heat or cool setpoint. The normally open (A1) relay conta ct is open and the normally closed (A3) relay contac t is closed. The fa n o perates as follows: fan is always intermittent (cycles with Y1 or W1).

Intelligent Recovery® Feature

Intelligent Recovery is a Honeywell trademarked feature for the way the thermostat controls heating and cooling equipment during recovery from the Unoccupied to Occupied setting. During recovery, the control point changes gradually rather than shifting immediat ely from the ene rgy savi ng setting to the comfort setting.

When Intelligent Recovery is used in he ating, the co ntrol point raises gradually, maximizing the use of the more economical first stage heat to br ing the sens ed tem perature to the desire d comfort setpoint. This minimizes using the typically more expensive second-s tag e heat.

Advantages of Intelligent Recov ery 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.

• The more economical first stage of he at is the primary heat source during recovery, minimizing use of the expensive second-stage heat.

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

• Heat cycling reduced, extend in g equi pm ent life .

RECOVERY FROM UNOCCUPIED

The heat pump heat recovery ramp is 3°F (1.6°C) per hour. This differs from the 5°F (2.8°C) per hour for conventi onal systems. The 3°F helps the system use the economical heat pump more and the expensiv e auxili ary heat less . The cooli ng ramp is 5°F, the same as for conventional systems.

GENERAL OPERATION INFORMATION

Cycle Rates

Subbase Auxiliary Relay

The Q7300 Auxiliary R elay output ac ts as a time-o f-day switch to be used with an eco nom izer m in im um pos iti on con trol. 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 pe riod and c losed duri ng the Un occupie d 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°F (10°C) to 60°F (16°C) 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, ou tdoor air changeov er control and a mini mum 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 cool 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 cooli ng to run mo re ofte n than if suitable outdoor air is permitted to enter the building.

The thermostat can take advantage of an economizer by connecting the subbase auxiliary relay contacts (A1 and A2) to control the economizer minimum position potentiometer. The contacts close during the Occupied period, allowing the economizer to ope rate norma lly. The contacts open during the Unoccupied period, disabling the minimum position feature of the economizer. The open contacts cause the economizer to drive dampers fully cl osed instead of staying at min imum 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 wate r heaters, lighting or baseboard heat. The additional loads are connected to the aux il iar y re lay co ntacts on the subbase. Th e 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. 19.
