WIRING DIAGRAM
Insta ation and commusioning
This device is dedicated to be incorporated in apartment electrical box with size of 4 or more poles
or a cabinet and can be attached on 35mm DIN rail.
Sensors and outputs wiring:
1. Scheme 1 “Loca Setp” (Regu ates output temperature to a fixed set point)
TS1: Regulated temperature TS2:not used TS3: Room temperature
R1: “Open” direction R2: “Close” direction
2. Scheme 2 “TSyphReC” (Regu ates output temperature to a variab e set point, ambient
temperature dependant)
TS1: Regulated temperature TS2: Ambient temperature TS3: Room temperature
R1: отваряне R2: затваряне
PARAMETERS:
„ROOM T.” – Set point of room temperature. [range = 10º C ÷ 45º C]. Factory= 25 º C;
. „Set T.” – Set point of water temperature. [range = -10º C ÷ 90º C]. Factory = 40 º C;
2. „±Hist I” – Hysteresis (fine regulation) [range 2º C ÷ 10º C] Factory= +5º C
3. „±Hist II” – Hysteresis 2 (coarse regulation) [range Hist I +2º C ÷ Hist I+ 15º C] Factory = +15 º C
4. „PulseDur” – Duration of signal pulses for “moving” the valve - either direction.
[range 0. 5sec ÷5.0 sec] Factory = + 1.0 sec;
5. „ON<>OFF” – Time constant of valve to change from fully open to fully close state.
[range 15 sec ÷ 250 sec] Factory . = 0 sec;
. „Period+” – Period of applying signal pulse for direction “open”
[range 5 sec ÷ 0 sec] Factory = 15 sec”
7. „Period-” – Period of applying signal pulse for direction “close”
[range 5 sec ÷ 0 sec] Factory = 15 sec”
8. „Setp=” – Mode of operation : at fixed set point (local) or with temperature compensation
based on ambient temperature
9. “dTAlarm” – Alarm temperature ,a ± margin from current set point. If temperature reading is
“outside” this margin device starts emergency “open” or “close” procedure [-35 º C ÷ 35º C].
Factory = 35

USAGE
Front pannel
Description
- two lines display
- 3x push buttons: for Up „Up↑”, for Down „Dn↓”, to select
„Set”
- Push button for selection of operation mode (stop/ automatic)
- Indicaton of alarm event – blinking of backlight (if a sensor is
defective)
Usage of buttons:
. button „Up- ↑”/„Dn-↓”, navigates among list of parameter screens previous/next;
activation with holding button "Set" increase / decrease selected value with
2. button „Set” change value of selected parameter
3. button „AUTO/STOP-” – selects the operational mode of the unit „AUTO”/ „STOP”
Avai ab e windows and usage
Window #1 - Main window
Displays temperature reading of sensors and operational mode of outputs.
Row 1: Outgoing water temperature "XX", "ZZ" relative valve status in percent.
If there is no sensor - „no” is displayed, if sensor is shor circuit or
resistance - “sc” is displayed.
Row 2: temperature set point "YY", "WW" ambient temperature when operating in ambient
temperature correction mode
Meaning of symbols:
” + ” - When submitting the “opening” command, the sign "=" is changed to "+"
” - ” - When submitting the "close" command, the sign "=" is changed with "-"
„ * ” - If the maximum movement is exceeded in the respective direction, the output effects are
discontinued (to save the life of the switching element) and the "sign" = "changes with " * "
„ R ” – While the room temperature displayed differs from the set point by more than -2÷ + °C,
the controller switches for 4 minutes in forced “opening” or “closing” mode to reach the set room
temperature more quickly. Visualized by blinking the "°c" sign alternatively with "R
When "STOP" mode is enabled, row 2 alternately outputs "-STOP--"
