Sensors Installation:
Pressure transmitter/temperature sensor
installed on the tube of evaporator outlet.
If the system is divided into several
evaporators, install pressure transmitter/
temperature sensor at each evaporator
outlet.
1. Finish connecting wiring before turning on power.
2. The RUN port (compressor signal) is a passive
port. If you add a voltage, it may cause the controller
burn out.
3. When using a transformer, ensure minimum power
of 15 VA (for 1 cont 1 EEV).
4. Wire diameter: 28 to 16 AWG
