Technical Description
Frost protection
The function involves the following: Heating operation is started at a
predefined room temperature in order to counteract the risk of damage that
otherwise can arise due to freezing.
Change over
The function involves the use of only one valve actuator which should be
wired to the cooling output terminal. This actuator then controls both the
heating water and the cooling water, which are transported in the same
pipe.
In winter, when heating is required, the valve opens if the water in the pipe
is warmer than the temperature setpoint. If the water is colder, the valve
does not open.
In summer, when cooling is required, the valve opens if the water in the pipe
is colder than the temperature setpoint.
In order to be able to use this function, you are required to mount an
external temperature sensor onto the water pipe through which supply
water circulates continuously. Wire the sensor according to the general
wiring diagram shown in the section entitled: Installation
Night cool
The function involves using cold air from outdoors for cooling the room at
night to the predefined level.
The function can only be managed in control systems that are connected to
a main control system via ModBus RTU.
Time-set setpoint restoration
The function involves adjusting the room temperature to the predefined
level when the controller switches to the AUTO operating mode.
The controller also switches automatically to the AUTO mode after a
predefined number of minutes after the most recent change, manually
entered on the room unit.
