EPH CONTROLS 20221108 RF Cylinder Thermostat

Product Information

The RFC – RF Cylinder Thermostat is a wireless enabled thermostat that can be mounted on recessed conduit boxes, surface mounting boxes or directly on walls. It has a boost function that allows the heating to be boosted for 1, 2 or 3 hours respectively. The thermostat also has a lock function that can be used to lock the keypad. The temperature control range is adjustable and it comes with a temperature sensor and an indicator. The thermostat is powered by batteries and has low battery indication.

Product Usage Instructions

1. Prior to setting the thermostat, it is necessary to complete all required settings described in the user manual.
2. Only qualified electricians or authorised service staff are permitted to open the thermostat.
3. Ensure that the thermostat is installed 1 metre from any metallic object, television, radio or wireless internet transmitter.
4. To reset the thermostat, press the button on the bottom of the thermostat, the front housing will detach from the baseplate. Insert the batteries into the thermostat. Press the reset button on the PCB, NO’ will flash on the screen. Rotate the hand wheel clockwise untilYES’ appears on the screen. Press the hand wheel once to confirm the setting. The thermostat has now been reset and the current temperature will appear on the screen.
5. To use the boost function, press the boost button once, twice or three times to boost the heating for 1, 2 or 3 hours respectively. +1H, +2H or +3H will appear on the screen. The boost function will override the programmer if the programmer is timed to be Off.
6. To lock the thermostat, press the hand wheel for 10 seconds. The keypad symbol will appear on the screen. To unlock the thermostat, press the hand wheel for 10 seconds. The keypad symbol will disappear from the screen.
7. To install the thermostat, press the button on the bottom of the thermostat. The front housing will detach from the baseplate. Insert the batteries (provided) into the thermostat. Mount the unit as described in section 3. Ensure the cable sensor is connected to terminals Con 3 and Con 4. Offer the baseplate up to the thermostat. Snap it into position to close.
8. To connect the RF thermostat with the programmer, lower the cover on the front of the timeswitch / programmer. Move the selector switch to the RUN position. On the timeswitch /programmer, press the Wireless Connect button and follow the instructions on the screen.

Mounting

Mounting of temperature sensor

• ON CYLINDER: To ensure accurate control of your cylinder, the temperature sensor should be mounted on the bottom 1/3 of the cylinder. It is essential that the sensing element is in direct contact with the cylinder and that there is no insulation between it and the cylinder. 60°C is the temperature level required in order to prevent the build up of legionella bacteria. The temperature sensor can be fixed to the cylinder using the provided foil tape.
• ON PIPEWORK: To ensure accurate control, the temperature sensor should be mounted on the pipework as tightly as possible. It is essential that the sensing element is in direct contact with the pipework and that there is no insulation between it and the pipework. The temperature sensor can be fixed to the pipework using the provided foil tape.

Mounting of thermostat

The thermostat should be mounted in a position that will make reading the display convenient. The thermostat can be fitted to:

1. Recessed conduit boxes
2. Surface mounting boxes
3. Directly on walls

Installation

• Press the button on the bottom of the thermostat.
• The front housing will detach from the baseplate.
• Insert the batteries (provided) into the thermostat.
• Mount the unit as described in section 3. Ensure the cable sensor is connected to terminals Con 3 and Con 4.
• Offer the baseplate up to the thermostat. Snap it into position to close.
