RFCV2 Cylinder Thermostat works

How a RFCV2 Cylinder Thermostat works

When a RFCV2 thermostat is calling for heat, it will operate according to the target temperature selected by the user.
The target temperature is defined by turning the dial clockwise for a higher target temperature or anti-clockwise for a lower target temperature.
If the cylinder temperature is lower than the target temperature then the thermostat will activate the demand for heat.
This will be indicated with a flame symbol on the screen.
Once the desired target temperature has been achieved, the thermostat will stop demanding heat, and the ame symbol will disappear from the screen.
The screen will always display the current cylinder temperature.

Mounting & Installation

Caution!

Installation and connection should only be carried out by a qualified person.
Only qualified electricians or authorised service staff are permitted to open the programmer.
If the thermostat or programmer are used in a way not specified by the manufacturer, their safety may be impaired.
Prior to setting the thermostat, it is necessary to complete all required settings described in this section.

This thermostat can be mounted in the following ways:

To a recessed conduit box
To a surface mounted box
Directly mounted on a wall

Mounting & Installation

Remove the thermostat from its packaging.
Choose a mounting location so that the thermostat can measure the temperature as accurately as possible.
- Choose a mounting location for the temperature probe as per the instructions on Page 8.
- Prevent direct exposure to sunlight or other heating / cooling sources.
Press and hold the release button on the bottom of the thermostat to detach the front housing from the base plate.
Insert the 2 x AAA batteries provided and the thermostat will turn on.
Plug the temperature sensor into the connector on the PCB.
Fix the base plate directly to the wall with the screws provided. Attached the front housing to the base plate.

Mounting of Temperature Sensor

Cylinder

Surface

The temperature sensor should be fitted on the bottom 1/3 of the cylinder.
Remove a section of insulation on the cylinder to reveal the copper surface.
Attach the temperature sensor to the surface of the cylinder using the foil tape provided.

Cylinder Pocket

Insert the temperature sensor into the appropriate pocket on the cylinder. Secure the temperature sensor to the pocket using the foil tape provided.

Pipe

Adjacent Room

Remove any insulation on the pipework to reveal the pipe.
Attach the temperature sensor to the surface of the pipe using the foil tape provided.
Mount the NTC sensor housing 1.5 meters above floor level.
Ensure the temperature sensor is secured tightly in the NTC sensor housing.

Note:

NTC sensor housing can be purchased as an accessory from EPH Controls.
Product code: NTC-Housing
