Page 20: Function Description
15. Function Description 15.1. Automatic Mode The unit will select heating or cooling mode automatically depending on the current inlet water temperature. When Ti ≥ Ts + P15, the unit enters cooling mode; When Ti ≤Ts – P16, the unit enters heating mode; Where Ti is inlet water temperature read by CN3, Ts is the set water temperature, P15 is the parameter value set in P15, and P16 is the parameter value set in P16. - Page 21 The fan motor has three speeds, with low speed in yellow color, medium speed in blue color and high speed in black color. A factory set unit has blue wire connected to FAN1 and black wire connected to FAN2. It is not recommended to change high speed to low speed manually because insufficient air volume in low air temperatures could damage the unit.

Note: Water Pump control in antifreeze protection will never be blocked. 16.6. Insufficient Water Flow Protection All outputs will be closed if water flow is insufficient or the water flow switch is malfunctioning. System uses two approaches to check whether the water flow is insufficient. Water Flow Switch System will check the state of Water Flow Switch one minute after the water pump is on.
