Operation and maintenance instructions
- Conditions:
• Only for GLOBAL LP or CLASS UNIT

•
The level of condensate is higher than a set Setting (approx. 1.5 cm).
It can also be activated if the pump is not present or defective
- Effects:
When activated, the supply and exhaust fans are stopped. This alarm is automatically reset when
the water level in the drain pan is lower than the setpoint, and the fans restart automatically.

• Only with post-heating, post-cooling or free cooling with heat wheel or modulating bypass option.
- Causes:
• T° sensor T5 located in the supply duct and connected to the TAC circuit is open, or short-circuited. This sensor is used
to regulate the post-heating or post-cooling function in the case of comfort T° control on T5 or to control the high
and low thresholds to limit the supply air temperature in the case of comfort T° control on T2.
