Rada 32RMX Temperature Controller

An electronic recirculating valve, incorporating a digital temperature display, suitable for multiple showers and washing applications.

The unit incorporates an electronic LED temperature display and is approved to BS 3456. The circuit temperature is controlled within ± 1.5°C of the set temperature.

Connections:

Inlet and outlet - 1¼" BSP standard.

Operation:

In precisely controlling the temperature of circulating mixed water, the Rada 32RMX performs two functions:

• Mixes hot water with cold and recirculating the water to a safe, pre-determined outlet temperature when showers or washing points are in use.

• Maintains the temperature in the circuit when no draw-off is taking place.

Electrical:

• Supply voltage: 12V AC via a separate transformer PT 220 (220-240V).

• Power consumption: 6 VA.

• Electronic circuitry protection: 500mA quick blow fuse (fitted).

• Cable entry: Base threaded to accept 20 mm conduit.

Pressure:

• Maximum static pressure: 10 bar.

• Maximum maintained pressure: 7 bar pressure loss.

Environmental conditions:

• Ambient temperature range: 0-60°C.

• Ambient humidity range: 0-100%RH.

Performance:

• Circuit temperature control: within ±1.5°C of the set temperature.

• Digital temperature display accuracy: ±1°C within the range 30°C to 60°C.

Materials:

• Base: Nickel plated gunmetal.

• Cover assembly: Aluminium.

• Thermister cap: Phosphor bronze.

Accessories:

• PT220 transformer assembly.

• Rada dial type thermometer.
