Package—Installation Instructions
Check thermostat and subbase suitability for the heat-
ing, 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.
Type of Heating System
to be Controlled

Pilot (IP), and Standing Pilot (SP)
Heat Pump
Hot Water Zone
Oil
Vent Damper
Warm Air Zone

If thermostat is not compatible with the system being controlled, the system will not operate. No hazard exists. The thermostat
will not be damaged unless it is used to directly control a line voltage system. A Honeywell R841 or R8239D1015 Isolating
Relay must be added to the thermostat control circuit for proper system operation.

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 virtually all heating,
cooling or heating/cooling systems. Refer to Table 1 for
additional thermostat compatibility information.
Conditions/Compatibility
• The R8239D1015 Isolating Relay or R841 Silent Switching
Center must be installed in the thermostat control circuit.
• Compatible.
• 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.
• 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.
• Compatible.
• Honeywell damper motors are compatible.
• Some non-Honeywell damper motors require an R8239D1015
Isolating Relay in the thermostat control circuit.
