Assembly Instructions
M8098-EN
Spare part heat sensor (O/ID T25603)
Purpose
Replacement of heat sensor (BT 1, BT 2.x)
Precondition
WARNING!
Danger for unauthorized persons!
Conversion work may only be carried out by
specialist staff who have been trained accordingly.
Therefore:
–Keep unauthorized persons away from the work
area.
NOTE!
Knowledge of the Instruction Manual is a
precondition for carrying outconversion work on the
unit.
Procedure
DANGER!
Danger to life caused by electric current!
Touching conductive parts causes a direct danger
to life.
Therefore:
–For all work on the electrical system, for
maintenance, cleaning or repair work,
disconnect from the mains or disconnect all
phases of the external power supply and secure
them against being switched on again. Check
unit is isolated from power supply.
WARNING!
Danger of crushing due to rolling away or
tipping
With an uneven floor or when the castors are not
locked, there is a danger that the unit tips over or
rolls away causing crushing.
Therefore:
–Only install the unit on an even floor.
–Ensure that the castors are locked.

12.Reconnect mains plug and switch on main switch.
13.Press the key to switch on the unit and check it for leaks.
14.Proceed as follows in order to calibrate the temperature
sensor:
When setting partameters set DFM recognition to the
"integrated“ value (in Settings / Various), continue with Step 15.
When setting parameters set DFM recognition to the "modular“
value (in Settings / Various), continue with Step 16.

15. Temperature sensor main line ext 1..8 and temperature
sensor return line ext. Proceed as follows in order to calibrate
1..8 , if necessary, the temperature sensor:
With a constant deviation set parameter Sensor… offset under
Service / Calibration / Temperature.
With a linear deviation, set parameter Sensor… asc.cor. under
Service / Calibration / Temperature.
