ZigBee remote control thermostat
ZED-TCM-M

Key features

Full remotely confi gurable thermostat
Wide 3 digit display
4 buttons
Battery powered
Internal antenna

This is a radio battery powered thermostat that can be connected to a PC-SCADA or PLC through ZigBee and one of the Gateways 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. 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. The actuator must be managed from PLC or by some devices such as ZED-TIREL2. This is because this thermostat is not equipped with relay output.
