Thermostat type
Twotypesofthermostatcanbeutilizedfortemperaturecontrol.
Electronic thermostat (NTC sensor)
Disconnected sensor error alarm (NTC sensor failure) is sent when the measured temperature is > +100ºC
Short circuited sensor error alarm (NTC sensor failure) is sent when the measured temperature < - 60ºC
Mechanical thermostat
AmechanicalON/OFFthermostatcanbeconnectedatterminalsC&T.
No detection of faulty thermostat is provided when an ON/OFF thermostat is used.
Automatic thermostat selection
The Thermostat parameter displays the type of thermostat connected to the controller: either a me-
chanical thermostat or NTC temperature sensor.
An NTC sensor is recommended for the temperature range -60 ºC to +100 ºC
A mechanical thermostat is recommended for temperatures below -60 ºC and above +100 ºC
Note: An NTC sensor error is not detectable when the NTC sensor is operating in automatic thermo-
stat selection mode.
