KTRRU-052.245#00
Room thermostat for cooling ceilings, flush-mounted, 24V AC/V DC, off/comfort/ECO switch
Electronic flush-mounted climate controller for controlling heating/cooling in 2- and 4-pipe systems for hotels, residential properties and business premises. In combination with the corresponding cover set, works with all common switch ranges. Compatible cover set no. JZ-007.xxx. Up to 5 valve actuators (24V~, closed when de-energised) can be controlled for each output. The switch can be used to select the off/comfort/ECO operating modes. Especially suitable for controlling cooling ceilings due to the option of dew point monitoring. In order to compensate for the inertia of control paths with cooling ceilings, the device has a temperature sensor input for activating an external radiation sensor (optional). The factory preset “zero point” of approx. 21…°C can be adjusted by +/- 5K in the device. The adjustment knob can be used to adjust the set temperature within the range +/- 3K of the set zero point. As a variant for public authorities that need the controller to be inaccessible to unauthorised people, the external sensor can also be implemented as a room sensor (optional). Using an internal Poti adapter, internal or external sensors, or both sensors, can be selected using adjustable weighting. Contact inputs for ECO function and OFF (frost protection).
