Assembly
Safety Function
The desired maximum temperature for example max. 42º C can be pre-set thanks to the safety function.
Adjustment
After the installation, the output temperature of the thermostat must be checked. A correction is necessary if the temperature measured at the output differs from the temperature set on the thermostat.
Maintenance
- To guarantee the smooth running of the thermostat, it is necessary from time to time to turn the thermostat from total hot to total cold.
- The mixer is equipped with non return valves. The non return valves must be checked regularly according to DIN EN 1717 in accordance with national or regional regulations (at least once a year). At this time, please also check the filter (A) situated on the MTC-thermoelement (94282000). After assembling the MTC-thermoelement, it is necessary to check the water temperature at the take off point as described under the headline „adjustment“. Before the adjustment, please check, if the warm water supply is activated and the maximum temperature of the warm water is available at the take off point.
