1.3 Main features
1.3.1 Thermal bypass
1.3.1.1 The AQH200-B and AQH240-B models are fitted with a fully automatic 100% heat
exchanger bypass mechanism. Time clock control and manual override are also
available
1.3.1.2 In automatic mode, the bypass will open when the indoor target temperature reaches a
pre-set value. Using the interface, the trigger temperature can be set b15°C and
25°C
1.3.1.3 The interface contains an optional frost protection system. During periods of very cold
weather, the fresh air supply fan will automatically reduce in speed to approximately 20%
of its commissioned setting to reduce the load on your heating system and avoid
possible freezing of the heat exchanger. During these periods, the extract fan will
increase in speed to its commissioned boost speed to maintain an even air pressure.
Using the interface, the trigger temperature can be set between -15°C and +5°C
