  • Page 5: Installation

    Installation Thermostat The thermostat must be installed on a DIN standard rail (EN 50022-35) in a normskåp with the applicable encapsulation class. The thermostat is IP20 classed and intended for installation in environments with a temperature range of -20 °C to +45 °C.

  • Page 6: Introduction

    INTRODUCTION Introduction The manual, like the thermostat, is divided into four operation modes so that you only need to read about the functions you will use. The thermostat operation mode can only be installed in the start menu, which is shown the first time the thermostat is started (read more about the start menu on page 8) or after it has been reset.

  • Page 7: Menu Navigation

    INTRODUCTION Menu navigation The functions in the thermostat are arranged in a system of menus and sub menus. The Main menu always contains three submenus TEMP PROGRAM SYSTEM There are further choices under these. The first time the thermostat is started, a number of requisite values must be set in the START menu (see page 8).

  • Page 8: Start Menu

    INTRODUCTION Start menu The start menu is used to quickly and simply set the three requisite basic settings; it is only shown the first time the thermostat is switched on (or if the thermostat is fully reset using the reset function). Begin by choosing a language, continue with the date and time setting, and finish off by setting operation mode and sensor.

  • Page 9: Display Mode

    INTRODUCTION Display mode The display mode is the thermostat's "normal" mode; the most important settings, statuses and functions are shown and set here. The display shows, alternatingly, the set point and current values at the same time as it always shows the operation mode and if the installation is switched on or off.

  • Page 11: Operation Mode

    Operation mode Heating Heating mode is used in homes, offices, storerooms and such like. With this operation mode, you can regulate the heating within a temperature range of +5 °C to +45 °C. The thermostat can be used as a floor thermostat, room thermostat or room thermostat with over heating protection for wood floors.

    The surface temperature is an average value and varies somewhat depending on the material and the thickness. Denser (harder) wood insulates less than softer wood, which increases the surface temperature. Also, the thinner the floor, the higher the surface temperature. Two sensors are required for over heating protection: a room sensor (sensor A) and an over heating protection sensor (sensor B).
  • Page 13 The temperature can be set between +5 °C and +45 °C. The thermostat works from the temperature that is set in the manual program where the factory setting is +22 °C.

TEMP ROOM THERMOSTAT If the room is very large or has large areas of glass, it can sometimes be better to regulate the heating via a room sensor.

  • Page 18: Operation Mode Cooling

    Operation mode Cooling Operation mode Cooling is used in home, office, storeroom environments and such like. In this operation mode, the thermostat works as a room thermostat for regulating air conditioning or other cooling within a temperature range of +5 °C to +45 °C. Energy saving programs are primarily adapted for home and office environments but can also be used for cooling, for example, storerooms.

  • Page 24: Operation Mode Industry

    Operation mode Industry Operation mode Industry is used to regulate the temperature of industrial processes, high temperatures or for the frost protection of sensitive installations. Temperatures within the ranges -15 °C to +75 °C and 0 °C to +170 °C can be regulated in this mode or the range can be limited to between -10 °C and +15 °C for frost protection purposes.
  • Page 25 Temperature hysteresis TEMP HYS The thermostat can be prevented from switching on and off the effect too often by increasing the temperature hysteresis. The hysteresis is the range the current value is permitted to deviate from the set point without the thermostat switching on or off the effect. A set hysteresis value of 0.3 °C and a set point of +40.0 °C means that the temperature (current value) can vary between +39.7 °C and +40.3 °C.

  • Page 26: Program Menu

    Program menu PROGRAM To be able to measure the temperature as accurately as possible, there are two temperature ranges, one from -15 °C to +75 °C and one from 0 °C to +170 °C. There is also a frost protection program to enable sensitive installations to be safeguarded against frost in a simple manner.
