If the sensors used to define the operating temperature are all faulty (open or in short circuit), the outputs are deactivated and
the fancoil is stopped.
Example:
M07
=0 sensor
AI1
used as remote sensor in combination with the internal sensor.
If sensor
AI1
is broken, the operating temperature becomes that of the internal sensor, regardless of the value of parameter
I06
.
If the internal sensor is broken, the operating temperature becomes that of sensor
AI1
, regardless of the value of parameter
I06
.
If both are broken, the operating temperature cannot be determined. Regulation is stopped.
For sensors used as automatic season changeover water sensor (2 pipe) or minimum thermostat sensor, if the sensor fails its
function is not excluded.
If a remote sensor is used as an automatic season changeover water sensor:
- in case of short circuit, the sensor temperature is considered to be high and the mode is considered to be heating.
- in case of open sensor, the sensor temperature is considered to be low and the mode is considered to be cooling.
If a remote sensor is used as the minimum thermostat:
- in case of short circuit, the sensor temperature is considered to be high and the minimum thermostat is considered to be
closed.
- in case of sensor open, the sensor temperature is considered to be low and the minimum thermostat is considered to be
open.
For input sensor

used as 0...10V (
M11
=10 and jumper JP1 set on position 0...10V) the message “
L-HI
“ (> 10V) is visual-
ized on the display B and

on the display A in alarm condition.
On the alarm page message
