Page 18: Modes Of Operation
ES SPLIT INSTALLATION MANUAL Modes of Operation Heating Operation Notes: At fi rst power up, a four-minute time delay is employed before the compressor is energized. Heat, 1st Stage (Y1) The compressor and loop pumps are energized 10 seconds after the Y1 input. Heat, 2nd Stage (Y1, W) Single-Speed Units The auxiliary heat relay will disconnect the compressor, and the auxiliary heat will operate normally. -
Page 19: Modes Of Operation
ES SPLIT INSTALLATION MANUAL Modes of Operation (cont.) Lockout Conditions During lockout mode, the appropriate thermostat lockout LEDs (if available) will illuminate. The compressor and loop pumps are de-energized and if the thermostat calls for third stage heating, emergency heat operation will occur. Lockout modes of any kind can be reset at the thermostat after a 5-second waiting period, which restores normal operation. -
