The RTM-01 temperature controller is used to control receivers (e.g. radiators, underfloor heating) depending on the temperature in the vicinity of the external NTC sensor. The device has the ability to adjust the set temperature using a potentiometer located on the front panel in the range of +5 oC ÷ +40 oC. For proper operation, the device requires the connection of an external NTC-03 probe. The probe is not included with the regulator and must be purchased separately. The probe cable is 3 m long and can be extended up to 50 m. The probes cannot be combined
