Installation and service instruction
15
Adjustments and setting general
2.5
Open up incoming cold water supply and fill the service water and heating circuits, bleeding off any
trapped air.
Check the operation and opening pressures of the safety valve.
Adjust the hot water temperature by having a hot water tap open at normal flow rate for a time.
Measure the temperature at the draw-off point with a thermometer.
The temperature should be approximately 50°C. It takes about 20 seconds to get stable tap water
temperature
50°C corresponds to a set point of approximately 1,5 on the actuator.
See chapter
for adjusting hot water temperature.
With a Micro HTC

Recommended set point for the actuator is 5 or 6.

Alfa Laval recommends that the tap water temperature is set to 10º less than the primary inlet
temperature. If a HTC the temperature must be 15º less than the primary inlet temperature.
NOTE
:
Make sure that no cold water is mixed with the hot water while making this adjustment.
The property owner must be instructed in the operation, setting and care of the unit. It is particularly
important to provide information about the safety systems and about hazards that may arise in relation
to the high pressure and temperature of the primary heating water.
Commissioning advice Micro RTC and Micro STC
2.6
The room thermostat has been set at the factory. If any function needs tuning, values can be changed
see
8 Activation of installer parameters.
Initially, the commissioning process should be carried out with the
factory settings.
Dismantlement
2.7
When the time comes for the substation to be dismantled and scrapped it must be disposed of in the correct
manner in accordance with local or national regulations.
User instruction HTC hot water actuator
2.8
Hot water temperature in apartments or one family houses can be set to about 50°C. If the temperature is set
too high, there is a risk of scalding. Setting the hot water temperature too low may result in unwanted
bacteriological growth in the hot water system.
