This thermostat offers you the flexibility to design heating and cooling programs that fit your needs. Features: • Separate program for each day of the week • Simultaneous heat and cool program storage • Preprogrammed temperature control • Four separate time/temperature settings per 24 hour period This thermostat is intended for use with a 24 volt system; do not use this thermostat with a millivolt or line voltage system. If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or electrician. Do not exceed the specification ratings. 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. ELECTRICAL DATA Electrical Rating: 20 to 30 VAC 50/60 Hz. or D.C. 0.05 to 1.5 Amps (Load per terminal) 1.5 Amps Maximum Total Load (All terminals combined) THERMAL DATA Setpoint Temperature Range: 45°F to 90°F (7°C to 32°C) Operating Ambient Temperature Range: 32°F to 105°F Operating Humidity Range: 0 to 90% RH (non-condensing) Shipping Temperature Range: -40°F to 150°F DESCRIPTION • LCD continuously displays set point, and alternately displays time and room temperature • Temperature override until next program period • Manual program override (HOLD temperature) • °F/°C convertibility • Temperature range 45° to 90°F • Eight terminals for single or two-transformer systems • O/B terminal for heat pump systems • Armchair Programming Capability PRECAUTIONS 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. WARNING! Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard. 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. SPECIFICATIONS APPLICATIONS For use with: • Heat pump systems with up to two stages heat, one stage cool DO NOT USE WITH: • Millivolt systems • Systems exceeding 30 VAC and 1.5 amps • 3-wire zoned hydronic heating systems WHITE-RODGERS DIVISION PART NO. 37-5739A EMERSON ELECTRIC CO. Printed in U.S.A. Replaces 37-5613C 9797 REAVIS ROAD ST. LOUIS, MISSOURI 63123-5398 INSTALLATION REMOVE OLD THERMOSTAT 1. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. 3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. 4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL. 5. Install new thermostat using the following procedures. ATTACH THERMOSTAT BASE TO WALL 1. Remove the packing material from the thermostat. 2. If necessary, cut the non-electric heat jumper (see NONELECTRIC HEAT SYSTEMS) and/or the EMR jumper (see ENERGY MANAGEMENT RECOVERY). Check the setting of the O/B switch (see O/B TERMINAL SWITCH SELECTION). 3. If you want to program the thermostat before mounting the thermostat on the wall, see ARMCHAIR PROGRAMMING. 4. Gently pull the thermostat cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit. 5. Check that the SYSTEM switch is in the OFF position. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 3 through 5). 6. Place base over hole in wall and mark mounting hole locations on wall using base as a template. 7. Move base out of the way. Drill mounting holes. 8. Fasten base loosely to wall, as shown in fig. 2, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase. 9. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. NON-ELECTRIC HEAT SYSTEMS Read the following information before clipping the non-electric heat jumper. If you are unsure of your application, contact a qualified serviceperson. If your emergency or auxiliary system is non-electric (gas, oil, etc.) and will energize the blower, then jumper, W904, on the back of the thermostat base must be cut (see fig. 1). If your emergency or auxiliary heat system is electric and requires that the thermostat energize the fan circuit, do not cut...
