Instructions for installation and use

5.0 Enduser instructions, initial adjustment/setting

Domestic hot water control
Danfoss PTC2+P controller (Fig. 1) for domestic hot water. Set the
DHW temperature by moving the adjuster lever towards "+" (hotter)
or "-" (colder).
Start by turning the lever clockwise – until it stops/until you cannot
turn it any further. Then turn the lever counter-clockwise until the
temperature of the tap water is approx. 48°C during normal tapping
flow (7–8 litres per min.). The temperature should never exceed 55°C
to prevent limescale deposits building up in the water heater.
Option: Alternatively the Akva Lux TDP-F substations may be fitted with a
Danfoss PM2+P controller (Fig. 1b) for domestic hot water. Set the DHW
temperature by turning the adjuster lever towards red (hotter) or blue (cold-
er). Start by turning the lever clockwise – until the pin is opposite the blue
dot. Then turn the lever counter-clockwise until the temperature of the tap
water is approx. 48°C during normal tapping flow (7–8 litres per min.). The
temperature must never exceed 55°C to prevent limescale deposits building
up in the water heater.
NB! The indicator of temperature setting must be positioned be-
tween the blue and red dot, otherwise the controller will shut down.
Bypass or circulation thermostat
Thermostat (Fig. 2) that keeps the branch pipe warm in the summer
or regulates the circulation temperature if domestic hot water recir-
culation has been established in the hot water system.
The thermostat should initially be set to position 3.
Heating circuit, Differential Pressure Controller
The differential pressure controller (Fig. 3) reduces the high, fluctu-
ating pressure in the district heating network to a constant operat-
ing pressure. The differential pressure controller is initially set by the
plumber in connection with the commissioning of the substation.
If disruptions to the operation occur: noise in the radiator thermo-
stats or poor regulation capacity, it may be necessary to reset the
differential pressure controller to a lower or higher operating pres-
sure. We suggest that you contact your local plumber for assistance.
Heating circuit, temperature control
The room temperature is regulated exclusively using the radiator
thermostats.
Return temperature limiter
Return temperature limiters are used to limit the return tempera-
ture of radiators.
The return temperature limiter should be set to the required maxi-
mum return temperature, in compliance with the local demands.
Scale setting (indicative:
I = 10° C
1 = 20 °C
2 = 30 °C
3 = 40 °C
4 = 45 °C
I = 50 °C (max. temperature)
To ensure sufficient cooling and proper operation the HE return
temperature must be lower than the temperature set on the flow
controller.
