Function

• 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 touchscreen displays status and is also used to access all parameters, such as setpoint, hysteresis, fan speed, etc.
• 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 mold protection and automatic valve exercise ensures proper functionality and a problem-free installation over time.

Settings

The thermostat settings can be controlled in one of the following ways:

• Display buttons: user settings such as temperature setpoint adjustment and fan speed
• Parameter list: quick configurations for installer
• Modbus variables: advanced thermostat control via Modbus communication

Table 1 Buttons available in the display

Handling
The display behaves differently depending on the mode and the state that the thermostat is currently operating in. The thermostat can be in one of the following states:

• Off: Energy saving state where the thermostat neither heats nor cools. No background light is lit, only the On/Off button is shown.
• Standby: Energy saving state where reduced heating or cooling takes place.
• Occupied: Comfort state when someone is present in the room. Optimal heating and cooling takes place.

The thermostat can be in three different modes when in Standby or Occupied state:

• Idle mode: The thermostat has been inactive during a set time span.
• All buttons and segments, except the two arrows, are dimmed down in the display.
• Active mode: The thermostat is activated, but no changes are made.
• The display shows either the calculated setpoint or the current room temperature.
• Setpoint mode: This mode is activated when pressing one of the arrows when in Active mode. Either the calculated setpoint or the current user defined setpoint adjustment are shown.
