to reduce the circulation
water temperature and a message “
PID:SUPERVISION
” appears in the
display.
Damping
– If the flue gas temperature drops below the predefined value and
does not rise above that level for a period of 300 seconds (factory-set damping
time) the controller enters the damping mode. When in that mode both blower
and feeder are stopped and the display reads “
PID:DAMPED
”.
II. Functions of the regulator
This chapter describes the functions of the regulator, the method of
changing the settings as well as navigation in the menu which is made using
the
pulse generator
(knob). The boiler's operational parameters are displayed
on the main screen of the controller. The user selects the operation mode and a
number of settings of the boiler according to their own needs.
II.1.
Homepage
During normal operation of the regulator, the
main page
is visible on the
graphic
display. Depending on the operation mode, one of the following
screens is displayed.
Pressing the
knob
of the
pulse generator
brings the user to the first
level menu. The first three menu options are shown on the display. Turn the
knob to move to subsequent options. Press the knob to select a given function.
Similar actions are made when changing parameters. To introduce changes it is
necessary to approve them by pressing the pulse generator when the
APPROVE
message is shown. If the user does not want to make any changes
in a given function, they should press the pulse generator when the
CANCEL
message is shown. To exit the menu select the
exit
option.
If necessary, you can use the
standby mode
button located on the
controller housing to rapidly turn off all actuators. This is an additional
safeguard feature for use in an emergency situation that allows you to power
down all controller actuators (fan, pump, valve).
NOTE: Power is not disconnected from the controller when it is in standby mode.
II.2.
Screen view
You can use this function to select one of four thermoregulator operation
main screens:
➔
CH screen (displays the current mode of operation of the boiler),
➔
main valve (displays the operating parameters of the main valve),
➔
valve 1 (displays the operating parameters of additional valve 1)
➔
valve 2 (displays the operating parameters of additional valve 2)
