operate in response to temperature changes in hydronic
heating systems.
L4006A breaks the circuit on a temperature rise to the
control setting. It is used for high limit or low limit
control. When used as a controller or as a low limit, a
separate high limit must be used.
L4006B makes the circuit on a temperature rise. It is
used as a circulator controller, delaying circulator
operation when boiler water temperature is below the
control setting.
L4006E,H includes a trip-free manual reset switch.
These models are designed to break the control circuit
whenever the temperature of the controlled medium
reaches the high limit setting. A reset button on the front
of the case must be pressed to re-establish the control
circuit. L4006H also includes bracket and clamp for
surface mounting on pipe or tank.
A plastic bag of heat-conductive compound is included
with the L4006A,B,E Aquastat® Controllers for use when
the sensing bulb is inserted into a well designed for a
large bulb than the one used on the L4006A,B,E. A
124904 Well Adapter, for use on old wells that do not fit
the L4006A,B,E immersion well clamp, can be ordered;
see form 68-0040, Wells and Fittings for Temperature
Controllers. A setting stop is included to prevent setting
above a desired temperature on limit.
If a well adapter or other accessories are needed, refer to
form 68-0040, Wells and Fittings for Temperature
Controllers, for part numbers and ordering information. |
