Wireless wiring center as part of the EasyLink 868 system. Communication between the room thermostat and actuator is wireless via the 868 MHz frequency band, a proven industry standard that ensures reliable performance in residential and commercial applications. No wall chasing or additional wiring is required, making the EasyLink 868 system ideal for renovation, retrofit, and modernization projects. The EV 8K-EasyLink wireless wiring center enables the control of up to eight heating zones via triac outputs. Its compact design allows for optimized and fast installation. One wiring center covers all common applications, including heating, heating/cooling operation, dew point monitoring, and pump logic control. Multiple channels can be assigned to a single thermostat, while individual channels can be excluded from cooling operation, making the system particularly suitable for mixed installations combining underfloor heating and chilled ceilings

Triac output, 8 channels (2 × 4 actuators, 6 × 2 actuators), multiple channels can be assigned in parallel to one heating zone/thermostat, supports up to 6 thermal actuators per channel at 3 W each (18 W total), NC/NO selectable via P1 jumper, push-in terminals for conductor cross-sections up to 2.5 mm², wireless communication via 868 MHz / LoRa®, PWM cycle time 5...20 min selectable via thermostat, frost protection at 5 °C via thermostat, adjustable valve protection function (duration and activation time) via thermostat, pump control with NO relay 2(2), ON/OFF delay: 2 min, dew point monitoring with TS 193683 dew point sensor (not included), RF commissioning and pairing via the user interface of the RF thermostat.
