4.6 PURGE DELAY OF THE PUMP
The controller offers the possibility to
stop the operation of the pump after an adjustable delay
once the heat demand has been completed.
The following choices are offered:
“OFF” The pump will stop immediately when the
heat demand has been satisfied. This selection
shall be selected on systems equipped with
motorised fast closing zone valves in order to
prevent noise from water hammering.
“15 sec to 60 min” delay where the pump will be
kept running to enable the pump to circulate
water into the system to equilibrate the heat in all
the building.
“ON” The pump is in continuous operation.
Required on particular heating distribution
systems.
4.7 AUTOMATIC HEATING
SHUT DOWN
When the outdoor sensor is installed and the unit then
operates in the “outdoor reset” mode, the controller offers
the user the possibility to automatically stop the boiler
when the outdoor temperature reaches an adjustable
value (0°F (-17°C) à 105°F (40°C). This characteristic is
especially interesting on the following applications:
-Heating systems equipped with many thermostats
where the user wants to prevent the operation of the unit
if one of the thermostats has inadvertently been
activated.
-Heating systems where the owner supplies heat to a
lodger
-Systems connected to a geothermic or air-water
heat pump where we do not want the electric boiler
to be operating unless the outdoor temperature
drops to a selected degree.
4.8 CONFIGURATION OF THE CONTROLLER
Since each type of heating distribution system is
designed to operate at water temperatures that are
particular to its operation, the proper configuration of the
operating parameters of this particular system is
important to maximize its performance.
In order to do this, the installer will first have to tell the
controller if the application is in automatic transfer mode
or autonomous electric mode. The selection is made by
selecting the position “Elect.” for the autonomous electric
mode
Or “Bi-Energ” for the automatic transfer mode on
the switch located at the back of the controller. This
selection will have to be made before applying voltage to
the unit. The default setting is the autonomous electric
mode
“Elect.”
