Installation, Operation & Maintenance

Wiring your CO2-X

GAS VALVE INPUT

It is possible for your CO2-X 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 the CO2-X to Natural or

Mechanical ventilation mode – see settings

for ventilation types.

When gas is supplied/in use – the CO2-X will

receive a signal from the gas valve and

display the [GAS IN USE] message. The CO2-

X will configure itself automatically to operate

in 'Kitchen' mode until the gas supply is

turned off – see 'Settings' for configuration.

Recommended for teaching areas with gas appliances such as laboratories and food technology rooms.

Rev 5 10-21

MAINS POWER/LINE IN

(110-120vac option)

Single-phase mains power is supplied to the [POWER/LINE IN] connector.

LINE & NEUTRAL ONLY.

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

also switch the Live (energise/ de-energise) a gas valve upon alarm levels of carbon

dioxide.

CO2 PRE-ALARM

This relay can send a signal to a Building Management System (BMS) or Merlin

panel when CO2 reaches pre-alarm level.

FAN ENABLE

This relay output can be connected to a fan switch which can energise fans via a

signal. This relay will switch on a fan from the current CO

temperature only or by the status of both (whichever is greatest) as follows:

>600ppm / >23°C (73.4°F) N/O: <550ppm / <22°C (71.6°F)

These levels cannot be altered.
