L4006A,B,E,H

Aquastat® Controllers

APPLICATION

These boiler-mounted, immersion type controllers

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.

Installing Immersion Well Models

(L4006A,B,E)

IMPORTANT

Obtain the best thermal response with a well

that snugly fits the sensing bulb. The bulb

should be inserted until it rests against the

bottom of the well. Use a well of correct length

and bend the tubing, if necessary, to provide

enough force to hold the bulb against the

bottom of the well. Do not make a sharp bend in

the tubing. A sharp bend can produce a break in

the tubing and cause a loss of fill. This condition

will cause the high and low limit controls to be

made continuously.

If the well is not a snug fit on the bulb, use the

heat-conductive compound as follows. Fold the

plastic bag of compound lengthwise and twist

gently. Snip the end of the bag and insert into

the well. Slowly pull out the bag while squeezing

firmly to distribute the compound evenly in the

well. Insert the bulb into the well. Bend the

tubing, if necessary, to provide force to hold the

bulb against the bottom of the well and to hold

the out end of the bulb in firm contact with the

side of the well. Wipe off any excess compound.

NOTE: Some models have an adjustable capillary

tubing length to 3 inches (76 mm). In these

models, pull out extra tubing from inside the

case, if needed.

Follow the boiler manufacturer instructions, if available;

otherwise, proceed as follows.
