Temperature adjustment
Set the desired recirculation system temperature by turning the
adjustment knob. The graduated scale shows the temperatures at which
the adjustment knob can be set.
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.
Temperature locking
After adjusting the temperature, the setting can be locked at the desired
value using the adjustment knob. Unscrew the locking screw at the top
of the adjustment knob, remove the knob and then put it back on so that
the internal groove couples with the protrusion on the knob holder nut.
When this lock is used, the reference of the indication of the temperature
values on the knob is lost. To restore it, completely unscrew the locking
screw. Reposition the knob on MAX value. Insert and tighten the locking
screw.
