The DuoFern room thermostat can be operated in a wide variety of applications. In all applications, you have the option of operating the room thermostat 2 with and without HomePilot. If you use the HomePilot for time control, switch the menu item 9-9-2 to 1.
In all applications, you have the option of registering a DuoFern window/door contact directly on the room thermostat 2. As soon as the window is opened, the room thermostat 2 will regulate the temperature down to 4°C and after the contact is closed, it will regulate it back up to the last setpoint.
Application 1:
This application is possible with the room thermostat (9485) and the room thermostat 2 (9485-1).
Direct control of electro-thermal control valves for floor heating by direct cable connection.
The room thermostat opens and closes the valves depending on the set and actual temperature.
In the same way, electric heaters, air conditioners, etc. can be connected directly to the DuoFern room thermostat and controlled. For these applications, a cable connection from the room thermostat to the corresponding device is required.
Control can be performed on the room thermostat itself or alternatively via the HomePilot. If the HomePilot is used for timed control, item 1 is selected in menu item 9-9-2.
Application 2:
This application is possible with the room thermostat (9485) and the room thermostat (9485-1).
Direct control of electro-thermal control valves for floor heating by radio. The room thermostat controls a DuoFern universal actuator 1- or 2-channel by radio. This opens and closes the valves depending on the setpoint and actual temperature.
In the same way, electric heaters, air conditioners, etc. can be controlled by radio via the universal actuator and the DuoFern room thermostat. For these applications, no direct cable connection from the room thermostat to the corresponding device is necessary.
Control can be performed on the room thermostat itself or alternatively via the HomePilot. If the HomePilot is used for time-based control, item 1 is selected in menu item 9-9-2.
Important: The DuoFern universal actuators are NOT registered on the HomePilot in this application, but are controlled exclusively via the room thermostat.
Application 3:
This application is only possible with room thermostat 2 (9485-1).
Control of DuoFern radiator actuator 2
A room thermostat 2 can centrally control up to 20 DuoFern radiator actuators 2. The individual radiator actuators 2 are registered with the room thermostat.
The setpoint temperature is used identically for all radiator actuators. In this application, you also have the option of specifying whether the actual temperature is also measured by the room thermostat or by the respective radiator actuator. As a rule, it makes sense to have the temperature measured by each radiator actuator 2 itself, but if the actuators are operated in niches or very cold walls, the measured temperature may deviate. In this case, the actual temperature from the room thermostat can be used. The changeover is made on the respective radiator actuator in the menu item SEn = Sensor external.
OFF = measurement in the radiator actuator,
ON = measurement in the room thermostat.
Control can take place at the room thermostat itself or alternatively via the HomePilot. If the HomePilot is used for time control, item 1 is selected in menu item 9-9-2.
