Central 24 V OEM connection unit (6 heating zones) for connecting room thermostats to valve-drives.

The OEM Basis : 24 V is a connection unit for connecting the room thermostats (e. g. OEM Thermostats) to the valve-drives (e. g. OEM Actuators). Furthermore, the OEM Basis provides the operation voltage for the connected devices.
Predominantly, it is used at the heating circuit distributor of a floor heating. The OEM Basis is appropriate for new constructions, as well as for the re-fitting of residential and commercial buildings with already existing floor heating systems.

Central 24 V OEM connection unit (6 heating zones) with pump control for connecting room thermostats to valve-drives

The OEM Basis : 24 V is a connection unit with integrated pump control. The total of 6 heating zones allows the connection of room thermostats (e. g. OEM Thermostats) to valve-drives (e. g. OEM Actuators).
Furthermore, the OEM Basis provides the operation voltage for the connected devices. The pump control shuts of the heating circuit pump, if none of the switch outputs of the connected thermostat are active. Predominantly, it is used at the heating circuit distributor of a floor heating. The OEM Basis is appropriate for new constructions, as well as for the re-fitting of residential and commercial buildings with already existing floor heating systems.

Central 24 V OEM connection unit heating/cooling (6 heating zones) for connecting OEM Thermostats heating/cooling to valve-drives. With integrated pump and boiler control and CO input for heating and cooling mode.

The OEM Basis Heating / Cooling serves as a connection unit in order to interconnect room thermostats (OEM Thermostats HK) and valve drives (e. g. OEM Actuators) in an easy and comfortable way. The unit has connections for the activation of a pump and a boiler or for further electrical consumers. The unit can be adapted to NC or NO systems by means of jumpers. Due to the possibility of an external change-over by means of a CO signal, this regulation system is appropriate for heating and cooling in single circuit systems.
