Installation, Operation & Maintenance Manual

CO2-TFT

Wiring your CO2-TFT

MAINS POWER CONNECTION

100-120V AC Single phase mains power should be supplied to the

[POWER/LINE IN] connector (Line & Neutral).

The CO2-TFT can also be powered from 12-24V supply – see [12-24V POWER INPUT].

GAS VALVE INPUT

It is possible for your CO2-TFT to receive a signal from a gas solenoid valve via Live & Neutral terminals

on our merlin panels when wired parallel.

To receive a signal you must ensure that you configure your CO2-TFT to Natural or Mechanical ventilation

mode – see settings for ventilation types.

When gas is supplied/in use – the CO2-TFT will receive a signal from the gas valve and display the [GAS

IN USE] message. The CO2-TFT will configure itself automatically to operate in 'Kitchen' mode until the

gas supply is turned off – see section 'Settings' for configuration.

This feature is recommended for teaching areas with gas appliances such as laboratories and food

technology rooms.

CO2 ALARM (Not a mains output)

This terminal can also connect to a building management system

(BMS) or to a Merlin panel to send an alarm signal upon alarm

levels of CO

. This terminal can also switch the Live (energise/ de-

energise) a gas valve upon alarm levels of carbon dioxide.
