Differential Pressure Restriction For Plate Heat Exchangers - Trane CCEB Installation Operation & Maintenance

Position of thermostat casing: fastened on outside panel of AHU casing
-
Triggering temperature: set to 70°C – value must not be changed
-
Sensor position: downstream of electric heater in upper area of airflow
-
- Function: alarm stop in case of overtemperature because of missing airflow
Connection box may reach high temperatures. For connection use heat-resistant cables (admissi-
ble operation temperature min. 110°C), for example silicone, Teflon or glass fiber insulated cables.
Connection scheme for electric heater according to the specified safety concept as minimum re-
quirement.
In case of dehumidification wheel downstream of electric heater ensure that control rotates the
wheel while electric heater is on (additional enabling contact). If control is not supplied by TRANE,
this feature has to be ensured on responsibility of client.
