Thermostatic control,
1164xxA series
Function A
At the set temperature, the valve plug (1),
controlled by the thermostatic balancing cartridge
(2), gradually closes the outlet to the minimum
2
flow (3). The outlet never fully closes to always
allow a minimum flow for temperature sensing
and to prevent recirculation pump dead-heading.
If the temperature decreases, the outlet increases,
causing flow and thus temperature to increase
back to the set temperature as shown in curve
1. If temperature exceeds the set-point, the plug
stays in the minimum closed position as shown
in curve 2.
Installation
Before installing the ThermoSetter, flush the pipes to make sure that impurities in system
will not interfere with valve performance. Strainers of sufficient capacity at the inlet from the
water main are highly recommended. The ThermoSetter can be installed in any position,
vertical or horizontal, following the flow direction indicated by the arrow on the valve body.
The ThermoSetter must be installed according to the diagrams given in this manual. It must
be installed to allow free access to for checking on operation and maintenance procedures.
