Construction and function

Summary / Functional description
The digital room thermostat is used for room temperature control in self-contained rooms. The room temperature is controlled via a valve which is activated through an actuator. When the room temperature has reached the nominal value, the valve will be closed. Setting of the nominal value by key stroke, visualisation on a large LCD display with blue backlighting. The backlighting is active when pressing the keys. Settings can be stored.

Application range
The digital room thermostat can be used in combination with the Oventrop two point actuators (M 30 x 1.5) for individual room temperature control

Installation

Extent of supply
Before installing the room thermostat, please check delivery for completeness and any damages caused during transit.

Switch off current supply

The installation location of the room thermostat must comply with the following conditions:

• The room thermostat must not be exposed to a direct heat source (e.g. sunlight) or cold source.
• A good air circulation must be guaranteed.
• The room thermostat must be easily accessible.
