Resumen del manual
Conventional recovery, however, starts recovery at the beginning of the programmed time period and uses the equipment to achieve the comfort settings as soon as possible. Adaptive Intelligent Recovery® calculates the recovery ramp based on the number of degrees away from the desired setpoint, previous equipment performance, and weather history to initiate recovery at the optimal time to achieve the comfort setting at the desired time. Once the recovery ramp is intersected, the setpoint changes from the setback setpoint to the comfort setpoint. This change snaps on the equipment and runs the equipment until the setpoint is reached. If the setpoint is reached too early or too late, the ramp is adjusted for the next days' recovery. 70°F SETPOINT TEMPERATURE ACTUAL TEMPERATURE 60°F SLEEP WAKE M6185A HEATING MODE Fig. 14.Temperature change in recovery. TROUBLESHOOTING GUIDE Refer to Table 12 for troubleshooting information. 17 68-0164—1 T8600D, T8601D AND T8602D CHRONOTHERMT8600D, T8601D AND T8602D CHRONOTHERMIV DELUXE PROGRAMMABLE THERMOSTATS Table 12. Troubleshooting Information. Symptom Possible Cause Action Display will not come on. Thermostat is not being powered. • Check for 24 Vac between R and C or W terminals. — If missing 24 Vac: — check if the circuit breaker is tripped—reset the circuit breaker. — check if the system fuse is blown—replace the fuse. — check if the power switch on the HVAC equipment is in the Off position—set to the On position. — check wiring between thermostat and HVAC equipment— replace any broken wires and tighten any loose connections. — If 24 Vac is present, proceed with troubleshooting. Temperature display is incorrect. Room temperature display has been reconfigured. Enter Installer Setup number 37 and reconfigure the display. Thermostat is configured for °F or °C display. Enter Installer Setup number 14 and reconfigure the display. Bad thermostat location. Relocate the thermostat. Temperature settings will not change. (Example: Cannot set the heating higher or the cooling lower.) The upper or lower temperature limits were reached. Check the temperature setpoints: • Heating limits are 40 to 90°F (4.5 to 32°C) • Cooling limits are 45 to 99°F (7 to 35°C) except D model cooling limits are 48 to 99°F. The setpoint temperature range stops were configured. Check Installer Setup numbers 34 and 35 and reconfigure the setpoint stops. Heating will not come on. No power to the thermostat. • Setpoint is above room temperature. • Check for 24 Vac between R and C or W terminals. — If missing 24 Vac: — check if the circuit breaker is tripped—reset the circuit breaker. — check if the system fuse is blown—replace the fuse. — check if the power switch on the HVAC equipment is in the Off position—set to the On position. — check wiring between thermostat and HVAC equipment— replace any broken wires and tighten any loose connections. — If 24 Vac is present, proceed with troubleshooting. Heating will not come on. Thermostat minimum off time is activated. Wait up to five minutes for the system to respond. System selection is not set to Heat. Set system selection to Heat. Heating setpoint is below room temperature. Check heating setpoint. Set heating setpoint to desired temperature. Cooling will not come on. No power to the thermostat. • Setpoint is below room temperature. • Check for 24 Vac between R or RC and C or Y terminals (D models requires power to R at all times). — If missing 24 Vac: — check if the circuit breaker is tripped—reset the circuit breaker. — check if the system fuse is blown—replace the fuse. — check if the power switch on the HVAC equipment is in the Off position—set to the On position. — check wiring between thermostat and HVAC equipment— replace any broken wires and tighten any loose connections. — If 24 Vac is present, proceed with troubleshooting. Thermostat minimum off time is activated. • Wait up to five minutes for the system to respond. • Enter Installer Setup number 33. Reconfigure minimum off time (if required). System selection is not set to Cool. Set system selection to Cool. Cool setpoint is above room temperature. Check cooling setpoint. Set cooling setpoint to desired temperature.

Symptom Possible Cause Action Heating or cooling come on momentarily and shut off Heat or cool circuit is opening up or becoming high impedance. Add resistor in parallel with load or install interface relay. System on indicator (flame=heat, snowflake=cool) is displayed, but no Fan operation set for 0 (conventional heat) when it should be set for 1 (electric heat). Enter Installer Setup number 2 and reconfigure the fan operation. warm or cool air is coming from the registers. Conventional heating equipment turns on the fan when the furnace has warmed up to a setpoint. Wait a minute after seeing the on indicat...
