Factory setting/Changing
JRGUMAT thermostatic mixing valves are fitted with
a thermostat allocated to a standard temperature
and set to a standard temperature at the factory.
This is apparent from the article number, it appears
in the centre of the temperature label D and is
indicated on the packaging. A change in standard
temperature can only be made within the limits
of the blended water adjustment range allocated.
Proceed as follows: Pierce the middle of the tem-
perature label D with the Allen key E. Turning the
screw F clockwise will increase the blended water
temperature while turning the key counterclock-
wise will lower it. The flow rate must be in the grey
shaded field "Nominal value tolerance ± 1K" (q.v.
nomogramme, page 48).
If the mixing valve is installed in a circulation net-
work, the circulation must be adjusted separately
at "zero removal". To do this, the overall flow rate
of the pump (100%) must be adjusted first. Then
set the flow rates, which lead to the mixing valve
and set the proportion required to cover heat loss
on the water heater.
A well-regulated circulation keeps the desired
blended water temperature constant even if no
blended water is drawn off.
