Heating/cooling relay, 1+1 NO contacts potential free 4A/250V AC, with DX technology. Bidirectional. Only 0.1 watt standby loss. Connection to the Eltako-RS485 bus. Bus cross wiring and power supply with jumper. To achieve this, simply connect the N conductor to the terminal (N1) and L to 1(L) and/or N to (N2) and L to 3(L). This results in an additional standby consumption of only 0.1 watt. When both relays of the FHK14 are switched on, 0.4 watts are required. If supply voltage fails, the device is switched off in defined mode. This heating/cooling relay assesses information about wireless temperature controllers or sensors. Possibly supplemented by window/door contacts, motion detectors, window handle sensor FFG7B-rw and wireless pushbuttons. As an alternative to a wireless temperature controller, the temperature information on the set and actual values can be obtained from the GFVS software. It is also possible to specify the set temperature via GFVS software and thus limiting the setting range of the wireless temperature controller.
