Description
Roth Mini shunt Plus is intended for supplying and connecting small floor
heating system to existing radiator heating systems. Two underfloor hes ting
circuits can be connected with the dual coupling. The room tempera- ture is
controlled via a thermostat with capillary sensor or a wireless room
thermostat and actuator (fixed-value temperature contra) Can be used on both
1- and 2-string systems and has a built-in temperature limit of 45°C.
Roth Mini shunt Plus:
| 1. Valve for thermostat or actuator | 7. Flow, secondary |
|---|---|
| 2. Circulation pump | 8. Regulation valve for water volume |
| 3. Air vent | 9. Bypass valve for 1- or 2-string systems |
| 4. Flow, primary | 10. Analog thermometer |
| 5. Return, primary | 11 Insulation Box |
| 6. Return, secondary |
| Pipe dimensions | Number of loops | May. pipe length |
|---|---|---|
| 10,5 mm | 1 | 70m |
| 10,5 mm | 2 | 2x70m |
| 16 mm | 1 | 90m |
| 16 mm | 2 | 2x90m |
| 20 mm | 1 | 120m |
| 20 mm | 2 | 2x120m |
Secure an equal length when installing 2 loops.
Assembly requirements
- The Roth Mini shunt Plus must be mounted in horizontal position as shown in picture 1
- It must be ensured there is a differential pressure of Min. 15 kPa and Max. 50 kPa
- The water temperature on the installation side should be min. 15°C higher than the underfloor circuit.
- Always flush the installation before attaching the Roth Mini shunt Plus.
Assembly
- Attach the Mini shunt Plus to a suitable wall. The pump will not cause noise due to the dense shunt body.
- Vent and perform pressure testing according to industry rules. Water filing, flushing and venting is optimized by combining the design of the shunt body with the air vent.
- Set between 1- and 2-string systems see page 6.
- Mount the thermostat or the actuator (wireless control only) on the valve
- Sensor or thermostat is placed approx. 1.7 m above the floor on an inner wall in a representative place.
- Set the pump to constant pressure. Normally. a setting as shown in image 2€ will be sufficient to achieve optimal comfort with minimum noise.
Indicator lights (LEDs)
(2A)
Signal display
LED is lit up in green in normal operation
LED lights up/flashes in case of a fault
(2B)
Display of selected control mode AP-v, AP-c and constant speed
(2C)
Display of selected pump curve ( I, I I, I I) within the control mode
(2D)
LED indicator combinations during the pump venting function, manual restart and key lock
No light in LED = No power
Setting of Mini shunt for 1- or 2-string system, picture 3+ 4
(The factory setting is 2-string)
- 2-string system 2.5 mm Allen screw must be completely at the bottom, see picture 3.
- L-string system, 2.5 mm Allen screw must be set in relation to the desired bypass water volume. Figure 4 shows the percentage of water that is passed through the bypass screw at the various settings.
