Notes:
(a) The two-way valve is very important to prevent dew condensation on the floor and radiator while cooling mode;
(b) Type of thermostat and specification should be complied with installation of this manual;
(c) The by-pass valve must be installed to secure enough water flow rate, and should be installed at the collector.
CASE 2: Connection between the Electric Heater and the Main Unit
Two groups of electric heaters are available, as well as control terminals for two groups of auxiliary electric
heaters. These two groups of electric heaters can be activated at the same time. When only one group of the
electric heater is installed, please follow the wiring of any group of the diagram shown below.
(1) See the following statement for installation of two groups of auxiliary electric heaters, including wiring of the
AC contactor, the thermostat and the tank-type electric heater.
