TFC Boiler Plus Optimum Vibe Installation Instructions

OPTIMUM VIBE PROGRAMMABLE THERMOSTAT - INSTALLATION INSTRUCTIONS
Transmitter
The OPTIMUM VIBE is a radio frequency programmable thermostat. It MUST be installed by a qualified person, in
accordance with best practise and current IEE wiring regulations. Before programming, complete all set-up instructions.
The control set - when configured for T.P.I. control - meets the UK Government BEIS Department's criteria for Class
IV control, contributing 2% towards energy efficiency of the system.
The transmitter is battery-powered (2 x AAA alkaline); the receiver is mains-powered, with volt-free switching.
The control set uses the license - free 868 MHz radio band to communicate between transmitter and receiver
Installation procedure: transmitter and receiver positioning
The receiver will normally be located close to the heat source, and should derive it's mains supply from the same
circuit that powers the heater / boiler. However avoid locating it directly next to the boiler's case - see
The transmitter should be located within the property bearing in mind the following requirements:
The transmitter has an on-board temperature sensor, which it uses to detect ambient temperature, and calculates
whether to send a demand or no-demand signal to the receiver. The transmitter should be located in a main living
area, where it is visible, has a free air-flow and is not unduly influenced by draughts or extraneous heat sources:
radiator / direct sunlight / lamp— please refer to the diagrams below:

The radio-frequency signal range is 20 to 30 metres in conventional brick / timber / tile structures. Note that me-
tallic materials such as reinforced concrete and foil-backed plasterboard will reduce or in some cases block the ra-
dio frequency signals. It is best to position both transmitter and receiver so that they are not close to large metallic
objects, and bear in mind that mirrors reflect radio waves in the same way they reflect light.
Transmitter - installation
Place 2 x AAA alkaline batteries in the battery compartment at the back of the transmitter; ensure correct polarity.
Set the time and day: After inserting batteries, the transmitter will jump to time-setting mode, or during normal
operation, touch SET for five seconds, change the minutes, touch SET, change the hours, touch SET, change the
day, touch SET. Then touch the ON/OFF icon to put in run mode. Full set-up can be completed later.
The transmitter can be wall-mounted, or placed on a table-top or counter, using the back-plate or the stand includ-
ed in the carton. If wall-mounting, fix the back-plate to the wall observing the UP ↑ ↑ marks, align the top two
recesses on the back of the transmitter, to the top two lugs on the back-plate, then rotate downwards to 'click' the
other two lugs in place. Reverse this procedure to remove the transmitter from the back-plate. Note that - if you
hold the transmitter for longer than a few seconds, it will start to detect your body temperature, rather than the
ambient room temperature, and this will affect the calculation of demand / no demand for heat. Replace the
transmitter onto the back-plate or stand so that it will again start to detect the ambient room temperature.
