Appendix Flow vs. Temperature Setting Guide

The following graph Indicates the water temperatures the Thermostatic AE 12 can achieve at different flow rates. The
graph shows the maximum and minimum temperatures achievable for the 12 kW unit with an inlet water temperature
of 50°.
Fig. 8
As water temperature varies throughout the
year adjustments to the Temperature
Adjustment Spindle and/or the flow rate
may be required.
We recommend setting the temperature
adjustment spindle to the maximum setting.
(see graph above).
If necessary, adjust the outlet service valve
until the water comes out of the tap at the
desired temperature (increase flow for
cooler water, decrease flow for hotter
water). The heater will then maintain the set
temperature in the summer months
reducing the power automatically.
When inlet water temperature increases
during the summer months, the heater will
maintain set temperature by reducing the
power automatically. In cases of extremely
warm incoming water supply, open service
valves fully to ensure maximum flow through
the unit.
