Page 22: Control Logic For I Control For S1 (300029=1)
Page 20 Control Logic for I Control for S1 (300029=1) For 2-Pipe system with Modulating Valves (300046=0) COOL MODE When unit is turned on in cooling mode. a) If Tr ≥ Ts + 1.8 °F (Modbus 300033 setting), MTV1 is turned on. AUX1 is closed. Fan is turned on at setting speed. DA2 is turned on at 10VDC for 2 minutes, then check Ti1, When Ti1<=46.4 °F, DA2 output is based on water temperature difference (Ti1/Ti2) and Modbus parameter 300027 setting PID calculation. -
Page 23: Dehumidification Mode
Page 21 With Electrical Heater as primary heat source (300047=2) When unit is turned on in heating mode: When Ti2 ≤ 95 ºF (or Ti2 is broken) and Tr ≤ Ts – 1.8 ºF (Modbus 300033 setting), Fan is turned on at setting speed, EH is turned on. When Tr > Ts + 1.8 ºF (Modbus 300033 setting), EH is turned off. Fan is turned on at low speed. - Page 24 Page 22 If Ti2< 158 ºF, then unit keep original state. If the indoor coil temperature sensor is damaged or not connected, then the protection mode will be overridden and the unit will work according to the pre-heat and post-heat program. DEHUMIDIFICATION MODE When unit is turned on in dehumidification mode: AUX1 is turned on.
