Question about Pentair Thermalflo Hp 900 Heat Pump 117,000 Btu'S
The DDTC temperature display contains three LED’s with a decimal point between the first and second,
this display is also used to display an error code if for some reason there is a failure within the heater
control system or a DDTC internal fault. The DDTC will display the actual temperature or set-point
temperature or OFF, as selected by the user. When DDTC detects an error, the display will show Exx, where Exx is the error code of DDTC fault, indicate a
“soft lockout” error that means after these errors are fixed, the heater will resume normal operation and
restart immediately. Code ERR indicates a “hard lockout” error that means after these errors are fixed,
you need to reset the power of the heater through the switch on the bottom of the electrical junction box
on the right side of the cabinet.
your error code e02 means high temperature limit.
