On delivery the compressor has a set working level
signifying the compressor to start when the temperatu-
re drops at the compressor sensor (94) to 50° C and to
stop when the temperature arrives at 53° C. It is pos-
sible to increase these temperatures by two degrees
(52 and 55° C respectively) in oder to achieve a
somewhat higher hot water temperature with the power
switch in mode "1" (immersion heater not operational).
This can be done by changing the mode of the switch
for No 1 on the microprocessor board (34) to mode
"On". However, be aware that this means somewhat
adverse working conditions for the compressor, as this
effects the economies slightly negative.
Compressor
FIGHTER 200p is equipped with the function for perio-
dical temperature increase. This means that the tempe-
rature will be put up to 60° C at regular intervals. This
function is not set functional at factory. How-ever,this
function will become operational, if the switch No 4 on
the printed circuit card will be changed to mode "On"
and if the hot water priority is operational. This setting
allows a hot water increase once a week. Once a day
will be operational, if the switch No. 3 will be set in the
mode "On". Note that while this heating is operational,
the circulation pump is not operational and the main
part of the heating is done by only immersion heater,
which effects the economies slightly negative. Also
note that while this heating the immersion heater is
operational, although the power switch is set to "1".
Periodical temperature increase
NOTE!
Periodical temperature increase is
possible only if the hot water prioriti-
sing is operational.
If permanent operation of the circulation pump is desi-
red, FIGHTER 200P is even equipped with a switch
(18) to alter between permanent and automatic ope-
ration, that is when the control system decides if the
circulation pump has to be operational or not. See dia-
gram "Electrical connections" -"Circulation pump con-
trol".
NOTE! If permanent operation is chosen, the hot
water prioritising is not operational as desired.
The periodical temperature increase should not be
made active.
FIGHTER 200P is equipped with a three-mode-switch
(25) in order to choose proper hot water operation, so-
called hot water prioritising.
The following three modes are available:
Off This means that the hot water prioritising is not
operational.
On Hot water prioritising is operational.
Auto Not used. Same function as mode ”On”.
Freezing protection and hot water prioritising
If hot water prioritising is operational all energy from
the compressor and the immersion heater (if mode "2"
is chosen on power switch) is used to heat up the hot
water. This happens normally when the temperature at
the immersion heater sensor (88) drops to 48° C. The
circulation pump will start again when the temperature
attains 51° C. These temperatures can be dropped
by two degrees (that is 46 and 49° C respectively) in
order to retarder the prioritising slightly. This is done
by changing switch No 2 on the printed circuit card
(34) to mode "On".
