Electronic climate controller with triac output (noiseless) Surface-mounted “ultra-thin” installation – Design Berlin 1000
Technical data
Application
Design:
Berlin 1000
This controller was specifically designed for heating/cooling regulation of 2-pipe systems used in hotels, homes and offices and can control up to 5 valve actuators (normally closed). The KTRTB”s internal sensor mea- sures the room temperature and activates heating or cooling de- pending on the deviation from the configured setpoint temperature. As the switching element used is a triac rather than a relay or bimetal, the system operates without both- ersome switching sounds. ECO function: if this function is se- lected, the temperature is adjusted down by 3 K in heating mode and up by 3 K in cooling mode.
