MEANS FOR PREVENTION AND PROTECTION:
Type Action
1
Anti frost of Solar Forced circulation of solar pump
2
Overheat of solar Forced circulation of solar pump
3 Thermal shock of solar “Slow” solar pump activation
4 Thermal shock of pipeline “Slow” solar pump activation
5 Anti frost of pipeline Trace heating/ Forced circulation of solar pump
6 Tank overheat “Vacancy” mode
Operation with “maximal thermal losses”
Auto cooling to “TBGood”
*Heat transfer to supplementary heating system
*Activation of emergency drainig valve
7 Pumps blockage Forced activation on certain period of inactivity
8 Current time lost (time not being set after power
failure with longer duration) Blinking display
* Available only for certain operational schemes

OTHERS:
„ Vacancy ” mode - forced cooling of tank (during night time) to have full heat storage for next day.
Selectable hysteresis 2 or 5 ºC Fault notification - entire screen blinking
Displays sensor failure message: „no” – no sensor; “sc” – sensor short circuited
Displays state of R1, R2 and R3
Manual activation/test of pumps
Important parameter change is password protected
Automatical switching to “Vacancy” mode if unit is left unattended and possible tank overheating is sensed
PWM output for HF pump speed control ; PWM – 1kHz

WIRING DIAGRAM
Attention!: Junction for heater’s neutral “N” should be made on external terminal block (not provided)!
All conections to PE should be made to external terminal block (not provided) !
- Power supply 230V AC – (internal and R1) – #17 (Live “La”); #16 („N”);
- R1: Pump/trace heating – #18 (switches Live); #15 („N”); – 5А max.
- R2: Electric heater – #20 (separate Live ”Lb”); #22 output – 16А max.
- R3: Pump2/Valve(Open/Close) – (switches Live) #13 (n.o); #14 (n.c. ) – 5А max.
Terminals 3 and 4 – level sensor input (measures conductivity of water)
Terminals 1 and 2 – PWM output for HF pumps
Attention!
Power supply should be applied via fuses:
- La – Circuit Breaker max 6А for trm. 17
- Lb - Circuit Breaker max 20А for trm. 20
-
If UPS is used, tem. 17/16 should be
supplied by UPS while trm.20 and heater
“N” should be connected before UPS
(directly to mains).
