ZED-TCMR

ZigBee remote control thermostat with relay output

ZED-TCMR

This is a radio battery powered thermostat that can be connected to a PC-SCADA or a PLC through ZigBee and one of the Gateway that belong to the 4-noks products family. It is equipped with a wide LCD display and 4 buttons in order to have a simple user interface.

It is also equipped with a bi-stable relay and so it may replace an ordinary thermostat giving a remotely controlled system. This thermostat has two different operating modes to activate output: heating/cooling mode or heating set temperature mode (Auto/Comfort/Background/Frost protection). This device periodically makes available the values of room temperature, current temperature and the operating mode currently active. All functions are remotely controllable.
