Equipment: Room temperature controller, mechanical, flush-mounted, 5...30°C, numeric scale, break contact, 230VAC, 10 (4) A, Application: Control or monitoring of temperatures in closed, dry rooms. Suitable for all types of heating. Valve actuator: closed when de-energized. If there are heating valves that are open when de-energized, these must be connected to the cooling output of the changeover switch (changeover contact), e.g. FTR 101.010. Up to 10 actuators for valves can be connected (break contact), up to 5 to the make contact on the changeover contact. The 55 x 55 mm variants fit perfectly into many 55 x 55 mm switch ranges without an intermediate frame.
