Description

The EU-R-8b Plus room regulator is designed to cooperate with TECH external controllers. It should be installed in heating zones. The regulator sends current room temperature and humidity readings to the external controller, which uses the data to control thermostatic valves (opening them when the temperature is too low and closing them when the room temperature has been reached).

Current temperature is displayed on the screen. The middle button ● enables the user to change the displayed parameter from current temperature to current humidity. The regulator enables the user to change the pre-set zone temperature permanently or for a period of time.

Controller equipment:

• built-in temperature sensor
• air humidity sensor
• wall-mountable casing

Low battery
If the regulator battery is low, the following message will flash on the screen: Lo. In order for the regulator to operate properly, replace the batteries (2xAAA 1,5V).

In order to replace batteries or connect the floor sensor, remove the back cover as illustrated in the pictures below
