5.1
Functional description
The digital room thermostat is used for the fan drive of Fan-Coil
units. The temperature of the fan convectors is controlled
continuously with the help of a valve which is activated through
an actuator. When the temperature has reached the set nominal
value, the valve is closed and the ventilator keeps running.
Setting of the nominal value by key stroke, visualisation on a
large LCD display with blue backlighting. The backlighting is
active when pressing the keys.
Operating functions: Heating, cooling, ventilation.
Fan speeds: slow, medium, fast or automatic.
Settings can be stored. Valve and Fan-Coil unit relay-controlled.
5.2
Application range
The digital room thermostat is suitable for the operation with
three-speed fans in combination with Oventrop two point
actuators.
