Anleitung Zusammenfassung
This electric or fossil fuel auxiliary. SPECIFICATIONS 1F94-371: 7 Day programming; residential applications ELECTRICAL DATA Electrical Rating: 20 to 30 VAC, 50/60 Hz with common 0.05 to 1.5 Amps per terminal 2.5 Amps maximum total load (all terminals combined) Standard Systems: Single-stage or two-stage compressor heat pump. THERMAL DATA Setpoint Temperature Range: 45° to 99°F (7° to 37°C) Operating Ambient Temperature: 32° to 110°F (0° to 43°C) Operating Humidity Range: 90% non-condensing max. Shipping Temperature Range: -4° to 149°F (-20° to 65°C) PRECAUTIONS WARNING! Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage thermostat and could cause personal injury and/or property damage. Do not use on circuits exceeding specified voltage. Higher voltage will damage thermostat and could cause shock or fire hazard. Thermostat installation and all components of the system shall conform to Class II circuits per the NEC code. CAUTION! To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete. NOTE Read all instructions thoroughly before beginning installation. This thermostat is intended for use with a low voltage system. Do not use on a line voltage system. Do not exceed ratings shown in the Specifications section, above. If in doubt about the electrical ratings of your heating/cooling system, have it inspected by a qualified heating and air conditioning contractor or licensed electrician. All wiring must conform to local and national electrical codes and ordinances. This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction. Part No. 37-6186B Replaces 37-6186A INSTALLATION INSTALLATION ATTENTION! This product does not contain mercury. However, this product may replace a unit which contains mercury. Do not open mercury cells. If a cell becomes damaged, do not touch any spilled mercury. Wearing nonabsorbent gloves, take up the spilled mercury and place into a container which can be sealed. If a cell becomes damaged, the unit should be discarded. Mercury must not be discarded in household trash. When the unit this product is replacing is to be discarded, place in a suitable container and return to White-Rodgers at 9797 Reavis Road, St. Louis, MO, 631235398 for proper disposal. REMOVE OLD THERMOSTAT Shut off electricity at main fuse or circuit breaker box until installation is complete AND the new thermostat is configured properly. Mounting screws Pull wires through this opening Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. Identify each wire attached to the thermostat using one of the labels enclosed with the new thermostat. Disconnect the wires from the old thermostat one at a time. DO NOT let the wires fall back into the wall. Install the new thermostat using the following procedures. ATTACH BASE TO WALL Remove packing material from the thermostat. Place fingers of one hand on the center top and bottom portion of the thermostat. Grasp the base in the other hand on top and bottom center and gently pull straight out. Forcing or prying on the thermostat will cause damage to the unit. Place the base over the hole in the wall where the wires come out and mark mounting hole locations using the base as a template. Drill 3.16” pilot holes, and install screw anchors in the wall. Run wires through hole in base and attach base to wall (see fig. 1). Insert the labeled wires into the appropriate terminals on the base and tighten the terminal screws. CONFIGURING AND PROGRAMMING Before the power is turned on, the thermostat must be configured to operate properly with the system. See the CONFIGURATION section of this manual. This thermostat can be programmed for automatic temperature control. Refer to Operating Instructions for programming.

Thermostat base and terminals 2 HEAT PUMP TERMINAL OUTPUTS HEAT PUMP TERMINAL OUTPUTS Refer to equipment manufacturers’ instructions for specific system wiring information. You can configure the thermostat for use with the following heat pump system types: HEAT PUMP TYPE 1. Single-stage compressor system; gas or electric backup. HEAT PUMP TYPE 2. Multi-stage or two- compressor system; gas or electric backup. HEAT PUMP TYPE 3. System requiring separate signals for heat (W1, W2, W3) and cool (Y1); gas or electric backup. This thermostat is designed to operate a single-transformer system. If you have a two- transformer system, cut and tape off one transformer. If transformer safety circuits are in only one of the systems, remove the transformer of the system with NO safety circuits. If...
