The room thermostat regulates the heating and/or cooling in a room via
on/off outputs for 2- or 4 pipe installations, and has a function for three-
speed fan control. The large LCD touch screen displays status and is also
used to access all parameters, such as setpoint, hysteresis, fan speed etc.
Dimensions, external (WxHxD)
95 x 95 x 50.5 mm
The unit has a built-in temperature sensor for controlling the room
temperature. The change-over function can be controlled using an
external PT1000 sensor or via a digital input connected to any potential
free contact. Functions such as mould protection and automatic valve
exercise ensures a proper functionality and a problem free installation
over time.
Installation
1. Separate the back plate from the display part with a small screw
driver. Insert the screw driver in the grooves at the bottom of the
unit.
