Available windows and usage
Window #1 - Main window
Displays temperature reading of sensors and operational mode of outputs.
-
Row 1
: temperature reading of solar sensor ”
XX
” / % of HF pump (if password is set),
Operational mode of the unit (electric heater): AUTO/OFF/ON/VAC.
Each one second the mode and state of the R2 output’s state is displayed alternatively
if R2 is switched on (activated) and
if R2 is switched off (not active).
Modes:
-
“AUTO” – auto mode, El. heater operates according to preset temperature setpoint and selected time zones.
-
“OFF” – El. heater is de-activated, automatically switches on as frost protection of tank if temperature is
<10ºC
-
“ON” – El. heater is automatically activated/de-activated to continiouslly keep TBGOOD temperature in
tank, it is de-activated if temperature is >TBGOOD.
-
“VAK” - vacancy mode of the system, the El. Heater is shut off (can be activated for defrost of tank). Cools
down the tank by tranfering back the available heat energy from tank to solar (if possible).
Mode of R1: if active – (solar pump), the symbol „S” blinks
Row 2
: reading ”
YY
” - temperature of main tank, reading “ZZ” – temperature of storage tank/boiler
Mode of R2: if active – (valve/pump), the symbol „A” blinks
-
If selected scheme of unit is #0 - „
TSyphTrH
” on Row2 currnet time as HH:MM:SS is displayed while
during defrost “
DeIce
” is displayed.
-
If level sensor is “open” or terminals 9 & 10 are open, also displays „
Fill-up
”
-
If selected scheme of unit is #1 -„
TSyphReC
” on Row2 currnet time as HH:MM:SS is displayed while if re-
circulation is activated - displays „
ReCirc.
”.
-
If selected scheme of unit is #7 -„
dT.EL.T1+R
” after ZZ :
-level is reached
- low level
* If there is no sensor „
no
” is displayed, if sensor is shor circuit or resistance is <600Ohm “
sc

Attention!
Keep all protections and comutation devices required by tank manufacturer to operate
the electric heater (circuit breakers, temperature regulator, safety temperature switch)!
DTSF3+ is not safety device as by means of
EN60730-1-Annex H
Attention!
Danger of electric shock!
All activities involving installation and commissioning should be done while electric power is off

LEVEL CONTROL
–
applicable in schmemes 0 and 7, for systems with valve for automatic filling up of fluid:
Connect terminal no.3 tank’s body, terminal no.4 connect to the electrode. The electrode must be electrically
insulated from tanks body and needs to be partially submerged in the water.
If the reguired level of the fluid is reached (the conductivity between tank’s boady and electrode is enough - the
electrode is partially submerged ) the filling is stopped (R3=Off)
If the level is decreased (there is no water between the electrode and tank body - no conductivity is senced) the
filling process is activated (R3=ON), if scheme 0 is used, the text “Fill-up” is displayed
,
if scheme 7 is used, the
icons
and
are blinking alternatively.
Забележка: 1. If the level sensor function is used, the sensor TS3 can not be used and have to be left free.
2. If the level sensor is not necessary, place bridge connection on
TS3
Connection to HF pumps:
Connect pump’s power supply to terminals no.18 and no.15. Connect pump speed input to terminals no.1 and no.2.
Initially the pump is activated on 100% for 10 sec. and this time the preset speed by parameter Pump%Lo and the
remaining temperature related conditions are followed.
