Option : “External Humidity Sensors” :
When an externally wired humidistat is fitted, its current humidity level (% RH) can be displayed. (Up to 3
sensors can be remotely wired on the 180 range, and up to 7 on the 350 range).
Option : “Other External Sensors” :
When fitted, the current level of other external sensors can be displayed : CO2 sensor (ppm), AQS Sensor 1
(ppm), AQS Sensor 2 (ppm), Smoke Alarm status, Volt Free Input 1 (Off or On), Volt Free Input 2 (Off or On).
Option : “Flue Detection Sensors” :
When fitted, shows the status of the two Flue detection inputs.
(Note when these connections are open the status is On, when closed the status is Off).
Option : “External Heaters” :
