TEMPERATURE CONTROLLER FOR 3 WAY VALVE
WITH OR WITHOUT EXTERNAL TEMPERATURE COMPENSATION
(IZOTHERMAL REGULATOR ) 3WM+A
DESCRIPTION
The unit is applicable for controlling the output temperature of electrically actuated 3 way
mixing valve:
- Mode 1"Setp C =ExtTemp" – compensation of regulated temperature according to external
temperature (isothermal regulation)
- Mode 2" Setp C =Local T" – fixed temperature preset by user
Characteristics:
1. Control commands for „Open" and „Close" for directions of motor driven 3-way mixing
valve.
2. Reads 1 or 2 temperatures
3. Parameters 16
4. User selectable mode of operation – fixed temperature or isothermal regulator
5. Push button Start/Stop
6. Power supply – 230 V AC, consumption <2VA
7. Outputs: 2 x – separate relays for commutation of :
- R1 n.o. – for "open" command
- R2 n.o. – for "close" command
8. LCD display – alphanumeric 8х2
9. Buttons for navigation – 3pcs. 1 Button for On/Off

WIRING DIAGRAM
Instalation and commusioning
Attention!
All activities involving installation and commissioning should be done while electric power is off
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.
Attention!
3WMreg is not a safety device as by means of EN60730-1-Annex H
Attention!
Power supply should be applied via fuses Phase-La / Lb 6A max.
1. Scheme 1 "Local Setp" (Regulates output temperature to a fixed set point)
TS1: Regulated temperature
R1: "Open" direction
2. Scheme 2 "TSyphReC" (Regulates output temperature to a variable set point, ambient
temperature dependant)
TS1: Regulated temperature
R1: отваряне
PARAMETERS:
„ROOM T."
– Set point of room temperature.
1. „Set T."
– Set point of water temperature.
2. „±Hist I" – Hysteresis 1 (fine regulation)
3. „±Hist II" – Hysteresis 2 (coarse regulation)
4. „PulseDur" – Duration of signal pulses for "moving" the valve - either direction.
for
[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 . = 60 sec;
6. „Period+" – Period of applying signal pulse for direction "open"
[range 5 sec ÷ 60 sec] Factory = 15 sec"
7. „Period-" – Period of applying signal pulse for direction "close"
[range 5 sec ÷ 60 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
Factory = 35
