Heating or Cooling and Heating/Cooling

New Construction Thermostat,

Wallplate and Subbase

Installation Instructions for the Trained Service Technician.

Preparation

Check thermostat and subbase (if used) suitability for the

heating, cooling, or heating/cooling system. Refer to Table 1.

Assemble tools required: flat bladed screwdriver, hand or

power drill with 3/16-in. drill bit, wire cutter/stripper or

sharp knife, bubble level or plumb bob and line.

Assure power is off to the heating, cooling, or heating/

cooling system at the main fuse panel. Most buildings have

a separate switch box or circuit breaker for disconnecting

power to the heating and cooling (if applicable) equipment.

This thermostat is compatible with most heating, cooling,

or heating/cooling systems. Refer to Table 1 for thermostat

and system compatibility information.

If thermostat is not compatible with the system being controlled, the system will not operate. No hazard exists. The thermo-

stat will not be damaged unless it is used to directly control a line voltage system. For proper system operation, a Honeywell

R841 or R8239D1015 Isolating Relay must be added to the thermostat control circuit.

Consult manufacturer for installation requirements.

Recycling Notice

This control contains mercury in a sealed tube. Do not

place control in the trash at the end of its useful life.

If this control is replacing a control that contains mercury

in a sealed tube, do not place your old control in the trash.

Contact your local waste management authority for in-

structions regarding recycling and the proper disposal of this

control, or of an old control containing mercury in a sealed

tube.

If you have questions, call Honeywell Inc. at 1-800-

468-1502.

TABLE 1—THERMOSTAT AND SYSTEM COMPATIBILITY.

Type of Heating System

to be Controlled Conditions/Compatibility

Electric (Line Voltage)—typical

baseboard and radiant

• The R8239D1015 Isolating Relay or R841 Silent Switching Center must be

installed in the thermostat control circuit.

Fan Coil Unit • Compatible. Assure correct subbase identity is selected for fan control.

Gas—Direct Spark Ignition

(DSI), Intermittent Pilot (IP), and

Standing Pilot (SP)

• Compatible. Assure that 24V control transformer common is accessible for

connection to thermostat cable conductor and power to the transformer is not

regularly interrupted by high temperature or limit operation.

Heat Pump • Compatible. Assure correct subbase identity is selected for fan control and

changeover control (O terminal for cool and B terminal for heat). Jumper Y

to W for heat pump compressor control.

Hot Water Zone • Honeywell 2-wire valves are compatible.

• Some non-Honeywell 2-wire valves require an R8239D1015 Isolating Relay

in the thermostat control circuit.

• Some 3-wire valves require an R8239A1052 Isolating Relay in the

thermostat control circuit.

a, b

Oil • Assure that the 24V control transformer common is accessible for connection

to thermostat cable conductor and power to the transformer is not regularly

interrupted by high temperature, purge cycle, or limit operation.

Vent Damper • Honeywell damper motors are compatible.

• Some non-Honeywell damper motors require an R8239D1015 Isolating

Relay in the thermostat control circuit.

Check control amperage

requirement.

Warm Air Zone • Most are compatible.
