RADIO HEATING COOLING ACTUATOR FHK61-230V

Wireless heating/cooling temperature relay for mounting in a control cabinet. Suitable for controlling electric heating and heating valves. This heating/cooling temperature relay evaluates data from Eltako wireless thermostats, temperature sensors, or controllers. Optionally completable with window/door contact, motion detector, window handle sensor FFG7B-rw, and wireless buttons. The upper rotary switch selects the operating mode: H1: Heating mode with PWM control, T = 4 minutes. (Suitable for valves with thermoelectric valve actuators.) H2: Heating mode with PWM control, T = 4 minutes. (Suitable for valves with motor-driven valve actuators.) H3: Heating mode with two-point control. K1: Cooling mode with PWM control, T = 15 minutes. K2: Cooling mode with two-point control. The lower rotary switch adjusts hysteresis and pulse width modulation effect: Leftmost position: lowest hysteresis 0.5°C. Middle position: hysteresis 2.5°C. Rightmost position: highest hysteresis 4.5°C. Between these positions, stepwise changes of 0.5°C are indicated by flashing the device's LED indicator. • Flush mounting, length 45 mm, width 45 mm, depth 33 mm. • Supply voltage 230 V. • If the supply voltage is interrupted, the switching state remains unchanged. • If voltage interruptions occur repeatedly, the device switches off in the predefined state. • Valves are controlled by a potential-free contact. • The LED indicator flashes during the learning process according to the operating instructions. During operation, it briefly flashes each time it receives a wireless signal. This product description is an automated translation of the original Finnish description.
