Section E3 —Without a Tank Sensor
The 363 is capable of operating the storage tank system without a storage
tank sensor. In this situation, once the 363 receives a
Mixing Demand the
control begins operation by trying to satisfy the system using the storage
tank. If the storage tank’s injection pump runs at a high percentage of output
and is still unable to satisfy the system, the 363 switches to the boiler’s
variable speed injection pump.
POLLING TIME (POLL TIME)
Once the 363 has switched to the boiler’s variable speed injection pump,
it must periodically check to see if the storage tank has accumulated a
usable amount of heat. This periodic checking is called polling. The polling period is an adjustable setting between 20 minutes and 12
hours. At the end of every polling period, the 363 switches to the storage tank’s variable speed pump. As long as the storage tank is
capable of satisfying the system, the 363 operates the storage tank’s variable speed pump. If the storage tank is not capable of satisfying
the system, the 363 switches back to the boiler’s variable speed pump. The control checks the storage tank at the end of the next
polling time.

STEP TWO MOUNTING THE BASE
Remove the control from its base by pressing down on the release clip in the wiring chamber and sliding the control upwards. The base
is then mounted in accordance with the instructions in the Data Brochure D 001.
STEP THREE ROUGH-IN WIRING
All electrical wiring terminates in the control base wiring chamber. The base has standard 7/8” (22 mm) knockouts which accept common
wiring hardware and conduit fittings. Before removing the knockouts, check the wiring diagram and select those sections of the chamber
with common voltages. Do not allow the wiring to cross between sections as the wires interfere with safety dividers which should be
installed at a later time.
Power must not be applied to any of the wires during the rough-in wiring stage.
