Wired Type Multi Zone Fancoil(F.C.U.) Control System

Model Number

WSF-700

Application

The WSF-700 system is designed to control the fan coil valve and the fan speed of the 5 slave zones with a single master thermostat located in a remote central zone.

The master thermostat can check and control the various conditions, and state of the slave zones’ thermostats such as the current temperature, the set temperature, operating hours, time reservation etc very conveniently through a valve control box based on the system communication.

System Composition

Features

• A master thermostat can check all working conditions of 4 slave thermostats and control them in a central zone. This system can control max 5 zones.
• Key Lock function
• AUTO CHANGE OVER function for the heating / cooling control is available.
• The program for anti-freezing and prevention of overheating is built in.
• 3-fan speed( High, Mid, Low) can be controlled either manually or automatically.
