range. The MATRIX.PC service software makes it possible to change this set-
point.
The standby mode is activated if a room temperature sensor is connected but no
room temperature setpoint, i.e. no control panel, is available (e.g. during con-
struction phase and drying of building).
The “standby mode” function is terminated if a specific room temperature setpoint
is set.
7.13.5 Indoor anti-freeze protection
This function ensures a frost-free condition when the unit is switched off.
At room temperatures < 4 °C, the valve is fully opened or electric heater on. The
fan is activated at the lowest speed, regardless of the inlet temperature.
If the room temperatures reaches > 6 °C, the valve is closed and the fan deacti-
vated. Normal regulation mode is activated.
7.13.6 Summer / winter compensation
This function requires connection to an external sensor.
This function enables a shift in the room temperature setpoint depending on the
ambient temperature.
Application example:
Starting from 26 °C outside temperature, it is requested to increase the room tem-
perature setpoint by 0.5 °C per 1 °C rise of outside temperature. The setpoint
should not be increased any further if outdoor air temperature reaches 32 °C.
Thus enter 26 °C as the start temperature and 32 °C as the end temperature.
The setpoint offset is calculated as follows:
(End temperature - start temperature) * 0.5 °C (the increase per °C external tem-
perature increase)
(32 - 26) * 0.5 = 6 * 0.5 = 3
The factory-set parameters can only be changed via the MATRIX.PC service soft-
ware.
