6 Auxiliary Heat Control
Included Items
If the Auxiliary Heat Control has been installed, then the ESP value has to be set.
For every increase in static pressure by 0.01 inWC, the ESP value should be increased by 1.
If the setting ESP value is inappropriate, the provided safety device will turn off the heater
according to the airflow.
* in.wc = inch Water Column, inAq
(Unit: CFM)
CAUTION
Do not use less than minimum airflow.
There is risk of fire or damage to the product.
!
CAUTION
Use the correctly rated power cable.
There is risk of fire or electric shock.
