Installation, Operation & Maintenance Manual

OPERATION

First Power Up

On connecting power, the CO2-TFT monitor enters a stabilisation phase for approximately 60 seconds –

during this period, your device not yet ready for operation.

a. CARBON DIOXIDE READING. Current CO

b. 0-10V ANALOGUE OUTPUT PROGRESS BARS. 0-10V analogue outputs 1 and 2.

c. FLAME ICON appears only when the CO2-TFT receives a signal from a gas valve and gas supply is

open/on and set to Natural or Mechanical Ventilation Type mode.

d. BOOST ON message appears when BOOST is activated - press and hold the touch button (f) for

three (3) seconds. The analogue outputs will run at optimum voltage (10V) for a pre-set number of

minutes. Boost can only be activated if either analogue outputs is set to CO2 or DUAL mode only.

e. MUTE message appears when the touch button (f) is pressed. The audible alarm buzzer must be set

to on or every 10 minutes and can only occur when gas is in use or KITCH. Ventilation mode is

selected and when CO

TOUCH BUTTON used to activate 'Boost' or 'Mute' dependant on the status and also to view the

screen for 10 seconds during screen saver mode.

g. TEMPERATURE READING. Current temperature in degrees Celsius or Fahrenheit. The temperature

will increase its accuracy over a 30 minute period upon power up.

h. GAS IN USE MESSAGE appears only when the CO2-TFT receives a signal from a gas valve and gas

supply is open/on. When the gas valve is closed, this message will not be displayed. Appears with

Flame icon.

BLANK (Natural or Mechanical mode), this is left blank when the current CO

550ppm. In Kitchen ventilation mode – this is constantly left blank.

AVERAGE CO

CALCULATION. The monitor will display the average CO

hours and appear only when current CO

ventilation type modes only.
