V.5.f) Pre-set room temperature
Once a room regulator with RS communication has been connected and activated in the controller menu
(
Fitter’s menu/Room regulator ), the user may adjust the pre-set room temperature.
V.6.
Manual mode
For the user's convenience, the regulator offers manual mode function. In this function, each executive
device may be activated and deactivated independently of others. It is an easy way of checking if the
following devices work properly: feeder, blow (fan), CH pump, DHW pump, additional pump 1, additional
pump 2, built-in valve1, built-in valve 2, valve 1, valve 2). Additionally, the user may adjust the fan speed
in manual operation mode using blow force function.
V.7.
Operation settings
NOTE: This submenu is available only when PID control is disabled - see: Controller operation
without zPID control .
V.7.a) Feeding time
This option is used to set the operation time of the fuel feeder. It should be adjusted to the type of fuel
and CH boiler used.
V.7.b) Pause time
This option is used to set the pause time of the feeder. The length of the pause should be adjusted to
the type of fuel used.
Incorrect pause time may result in inefficient operation of the CH boiler, i.e. unburnt coal left or failure
to reach the pre-set temperature of the CH boiler. Appropriate pause time ensures efficient operation of
the CH boiler.
V.7.c) Blow force
This function is used to control the fan speed. The setting range is 1-100% (it may be regarded as fan
gears). The higher the gear is, the faster the fan works. 10% is the minimum fan speed whereas 100%
is the maximum fan speed.
Initially the fan always operates at a full speed, which enables successful activation even if the
motor is dusty.
V.7.d) Operation in sustain mode
This option is used to set the operation time of the feeder and the fan when the CH boiler operates in
sustain mode.
V.7.e) Pause in sustain mode
This option is used to set the fuel feeding pause time when the CH boiler operates in sustain mode.
Incorrect setting of pause and operation time may result in farther temperature increase, unintended CH
boiler damping or lead to fuel ignition hazard in the fuel tank.
V.7.f) Fan in sustain mode
This option is used to set the fan operation and pause time in sustain mode.
V.7.g) Fan speed in sustain mode
This option is used to set appropriate fan gear (blow force) in sustain mode.
V.8.
Fuel granulation
This function is used to choose one of the two levels of fuel granulation: coarse or fine. For each level
there is suitable blow force and fuel feeding frequency programmed.
