Thermostats RTE 0/0 RTEV 0/0/0V RTEV 0/0 RTEV 0 Electronic thermostats Setting of temperature on the RTE 0/0 is done on the circuit board under the housing to prevent unauthorised persons from changing the selected temperature. Thermostats are designed to control heat directly or to be used as sensors in larger centrally controlled facilities. RTEV 0/0 is equipped with a dial for setting the temperature. The setting range can be limited on the back of the dial and the thermostat can be calibrated there as well, if necessary. RTEV 0V is also equipped with an alternating relay and can therefore be used for the regulation of heating or cooling. External sensors mounted in ventilation ducts or the floor can also be connected. RTEV 0/0 has a function switch for on/off connection as well as the optional connection of external sensors. A fixed temperature reduction of ºC can be activated by an externally connected contact, such as a weekly timer. The setting range can be limited and calibrated on the setting dial. RTEV 0 also has a built-in clock function in addition to the dial and the option of connecting external duct or floor sensors. The period for temperature reduction by ºC is, 7,, or 6 hours. The preferred period is set on the circuit board upon installation. The reduction period is activated by pushing the start button at the desired time of day. The clock is then set and the reduction period starts at that time every day automatically. An ongoing temperature reduction period can be interrupted with a push of the start button. The following day, the reduction period once again begins at the usual set time.

KRT900/90 KRTV9 KRTE Capsulated Thermostats Capillary tube thermostats and electrical thermostats with alternating contacts Capillary tube thermostats with alternating contacts for the control of heaters and fans. The housing is of thermal plastic. Convertible between 0/00 V and approved for 6 A at 0 V and 0 A at 00 V. KRT 900/90 both have internal dials but have different setting ranges. KRTV 9 has an external dial with an adjustable stop for the imum setting. Electronic thermostats are not subject to mechanical wear. Thus, they are very reliable and have longer durability. A sensor on a metres long cable is included with the KRTE thermostat. The sensor can be placed anywhere or fixed directly on the thermostat. The cable is easily extendable. The KRTE has an alternating contact and is approved for 0A at 0V.

KRT800 000 -stage thermostats, capillary tube -stage regulation is appropriate for the soft and economical control of heating output in e.g. fan heaters and air curtains. There are two types to choose from: KRT 800 with an adjustable temperature difference between the stages ( - C). 000 with a fixed temperature difference ( C) between the stages. Both are convertible between 0/00V and approved for 6A at 0V and 0A at 00V.
