Hose Heat Manual Mode
If the hose temperature controller does not see the Fluid
Temperature Sensor (FTS), it will shut off the hose heat
and give a flashing error alternating between:
SbEr = Sensor break error
H20.0 = Heat output 20%
The hose can be manually heated by turning the hose
back on with the hose switch and green light. The
up/down arrows can be used to adjust the default 20%
power output.
There is no monitoring or alarm in manual mode. You
must monitor the temperature by inserting a probe ther-
mometer inside the hose insulation against the hose.
The thermometer will read 10-20 °F less than actual
fluid temperature. Repair the temperature sensor or
cable as soon as possible to avoid damaging the heated
hose.
Do not allow hose to overheat during manual control.
Hose temperature, as indicated by a properly installed
hose thermometer, must not exceed 170 °F (76 °C).
Closely monitor hose temperature to avoid personal
injury or damage to property.
