Once the pump has stopped, P2 valve is set
at “0” (power supply is cut off).
The system operates until the temperature of
water in DHW tank has reached the value set in
TzCWU (read-out of T2 sensor), then it stops.
Once T1 or T3 temperature of solar
collector has reached the critical value of
TCOLkr , the regulator (despite the set
temperature of TzCWU has been reached) allows
to start P1 collector serving pump and to set P2
valve at the solar collector of higher temperature
in order to reduce the temperature of the
collectors below the value of
HP1 hysteresis.
Once the temperature of DHW tank has
reached the value of TCWUmax ( read-out of T2
sensor ), the regulator, in-spite of reached critical
temperature of the collectors ( TCOLkr ), stops
collector serving pumps to prevent collector
cooling down. It protects DHW tank from
overheating.
List of parameters available in „Settings” menu
TzCWU - set temperature of DHW tank.
Night cooling – YES / NO - switches on/off
night cooling mode active from 00
00
÷ 05
00
.
Night cooling ON – temperature of DHW tank
(read-out of T2 sensor), upon excess of
which, the regulator will activate night
cooling mode at 0
00
(provided that night
cooling function is enabled).
Night cooling OFF – temperature of DHW tank
(read-out of T2 sensor) to which the
regulator will cool down DHW tank (provided
that night cooling function is enabled and
temperature of
Tschł WŁ has been exceeded
within the period of time from 00
00
to 05
00
).
Alarm TCOLkr – switches on (YES) or off (NO)
the "Temperature of TCOLkr exceeded"
alarm. This function does not affect the
regulator operation. Setting this parameter
at "NO” causes the regulator will not produce
the alarm of exceeded
TCOLkr temperature
for T1 and T3 solar collector sensors.
14. SHUT DOWN
Access
This option displays screen windows, where you
can confirm that you want to shut down the unit.
After confirmation the controller is switched off.
Fig. 14.1 Shut down screen
The controller may be also
switched off in main screen by
pressing the encoder for 3
seconds. Confirmation screen will
be displayed like in Fig. 14.1
After confirmation the controller is
switched off.
