Honeywell Y8196A Installation Manual

Check thermostat and subbase 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 virtually all heating, cooling or heating/cooling systems. Refer to Table 1 for additional thermostat compatibility information.

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 controlcircuit.a
Gas—Direct Spark Ignition (DSI), Intermittent Pilot (IP), and Standing Pilot (SP)	Compatible
Heat Pump	Compatible. Assure correct subbase identity is selected for 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 controlcircuit.a Some 3-wire valves require an R8239A1052 Isolating in the thermostat control circuit.a, b
Oil	Compatible
Vent Damper	Honeywell damper motors are compatible. Some non-Honeywell damper motors require an R8239D1015 Isolating Relay in the thermostat control circuit.a Check control amperage requirement.
Warm Air Zone	Most are compatible.

a 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.
b Consult manufacturer for installation requirements. 

Honeywell Y8196A Installation

WHEN INSTALLING THIS PRODUCT…

1. Read these instructions carefully. Failure to follow them could cause a hazardous condition.
2. Installer must be a trained experienced service technician.
3. After installation is complete, check out product operation as provided in these instructions.

IMPORTANT: An incorrectly leveled subbase will cause the temperature control to deviate from setpoint. It is not a calibration problem.

LOCATION
Locate thermostat about 5 ft (1.5m) above the floor in an area with good air circulation at average temperature. Do not mount the thermostat where it may be affected by—

• —drafts, or dead spots behind doors and in corners.
• —hot or cold air from ducts.
• —radiant heat from the sun or appliances.
• —concealed pipes and chimneys.
• —unheated (uncooled) areas such as an outside wall behind the thermostat.

Run wires from the heating, cooling, or heating/cooling equipment to the new thermostat location.
