Note.
Where multiple sensors are used the overall accuracy of temperature measurement is reduced, this can be compensated for by trimming the parallel resistors
Siting of multiple room sensors for large spaces should be carefully considered to avoid significant temperature differences between sensors

2.26 CONTROLS CONFIGURATION, COMMISSIONING AND TESTING

A. ELECTRICAL INSTALLATION
1. Checks to ensure electrical safety should be carried out
by a competent person.
2. ALWAYS carry out the preliminary electrical system
checks, i.e. earth continuity, polarity, resistance to earth
and short circuit, using a suitable meter.
WARNING. Whilst effecting the required gas soundness test and purging air from the gas
installation, open all windows and doors, extinguish naked lights and DO NOT SMOKE.

B. GAS INSTALLATION
1. The whole of the gas installation, including the meter,
should be inspected and tested for soundness and then
purged in accordance with the recommendations of the
relevant standards listed on page 8, by the installer.
In IE refer to I.S.813:2002.
