2. The control output was energized for more than the “Minimum output on time”; (factory
setting 1 minute)
Note:
Control output Y12 delivers a control command which is inverted to the control command
at output Y14 that can be used for normally open valves.
Valve output can respond immediately and does not consider minimum On/Off time if
users manually adjust the setpoint via local HMI.
Error handling
Temperature out of range
Factory setting of the heating/cooling setpoint in Protection mode is Off, i.e. overheating/frost
protection is disabled.
In this case, when the room temperature is out of range, i.e. above 49 °C or below 0 °C, the
temperature displays and flashes at “0 °C” or “49 °C”, and the thermostat continues to work.
Sensor error
When the internal sensor is not working properly, “Er1” is displayed.
