Heating-cooling relay with 4 channels, 1 NO contact each 4A/250V AC, isolated from the supply voltage, with DX technology. Bidirectional. Stand-by loss only 0.1 watt. Connection to the Eltako RS485 bus. Cross-wiring bus and power supply with jumper. To do this, simply connect the N conductor to the clamp (N) and L to K(L). This results in an additional standby loss of only 0.1 watt. If all 4 relays are switched on, 0.7 Watt is required. If the supply voltage fails, it is switched off in a defined way. This heating-cooling relay evaluates the information from radio temperature controllers or sensors. Window-door contacts, motion detectors, window-grip sensor FFG7B-rw and radio button may be added. As an alternative to a radio temperature controller, the temperature information about setpoint and actual values can also be obtained from the GFVS software. Furthermore, the GFVS software can be used to set the target temperature and thus restrict the setting range of the radio temperature controllers. Upper rotary switch for the adjustable hysteresis: Left stop: Smallest hysteresis 0,5º. Center position: Hysteresis 2,5º. Right stop: Largest hysteresis 4,5º. In between, divided into 0,5º steps. Middle rotary switch for the control types. The LED below the upper rotary switch accompanies the programming process according to the operating instructions and indicates control commands during operation by short flashing.This text is machine translated.
