electric bypass valve is required to be installed between the inlet and outlet pipes of each evaporator with the
maximum bypass water flow rate through the valve at the fully open state no more than 40% of the unit rated
water flow. UC800 outputs 0~10VDC signal to adjust the opening of the two-way electric valve to make the
leaving water temperature of the unit gradually approach set-point, thereby improving defrosting and heating
performance of the unit. The detailed installation is shown in
