BRYANT THERMOSTAT WIRING DIAGRAMS ARE ONLY ACCURATE FOR MODEL NUMBERS BEGINNING WITH TSTAT_______. 2. WIRING MUST CONFORM TO NEC OR LOCAL CODES. 3. SOME UNITS ARE EQUIPPED WITH PRESSURE SWITCH(ES), TEMPERATURE SWITCH, OR 5-MINUTE COMPRESSOR CYCLE PROTECTION. CONNECT 24-V FIELD WIRING TO FACTORY-PROVIDED STRIPPED LEADS. 4. A LIQUID-LINE SOLENOID VALVE IS REQUIRED ON SOME UNITS. 5. THERMOSTATS ARE FACTORY CONFIGURED WITH 5-MINUTE COMPRESSOR CYCLE PROTECTION AND 4 CYCLES PER HR LIMIT. SEE THERMOSTAT INSTALLATION INSTRUCTIONS FOR DETAILS. 6. TO STAGE ELECTRIC RESISTANCE HEAT, CONSULT OUTDOOR THERMOSTAT INSTALLATION INSTRUCTIONS. 7. FOR DUAL FUEL THERMOSTATS, UNDERLINED LETTER ON DUAL TERMINAL INDICATES ITS USAGE. FOR EXAMPLE: O/W2 MEANS O O/W2 MEANS W2 OUTDOOR TEMPERATURE SENSOR MUST BE ATTACHED IN ALL DUAL FUEL INSTALLATIONS. JUMPER WIRE BETWEEN O/W2 AND L THERMOSTAT TERMINALS MUST BE PRESENT. 8. Y1 AND O CONNECTIONS TO 2-STAGE FURNACES MAY NOT EXIST OR MAY ONLY BE A WIRE RATHER THAN A SCREW TERMINAL. SHR EHR ODT LEGEND 24 VOLT FACTORY WIRING 24 VOLT FIELD WIRING FIELD SPLICE CONNECTION OUTDOOR THERMOSTAT EMERGENCY HEAT RELAY SUPPLEMENTAL HEAT RELAY providing electrical potential to second heater sequencer (if used). If outdoor temperature falls below setting of outdoor thermostat (field-installed option), contacts close to complete circuit and bring on second bank of supplemental electric heat. When thermostat is satisfied, its contacts open, de-energizing contactor and sequencer. All heaters and motors should stop. DEFROST The defrost control is a time/temperature control which includes a field-selectable (quick-connects located at board edge) time period between defrost cycles (30, 50, or 90 minutes), factory set at 90 minutes. The electronic timer and defrost cycle start only when contactor is energized and defrost thermostat is closed. Defrost mode is identical to cooling mode except that outdoor fan motor stops and second-stage heat is turned on to continue warming conditioned space. To initiate defrost, the defrost thermostat must be closed. This can be accomplished as follows: 1. Turn off power to outdoor unit. 2. Disconnect outdoor fan motor lead from OF2 on control board. (See Fig. 15.) Tape lead to prevent grounding. A97413 3. Restart unit in heating mode, allowing frost to accumulate on outdoor coil. 4. After a few minutes in heating mode, liquid line temperature should drop below closing point of defrost thermostat (approximately 30°F). 5. Short between speed-up terminals with a flat-bladed screwdriver. (See Fig. 15.) This reduces the timing sequence to 1/256th of original time. (See Table 3.) 6.
