PROGRAMMING
HEAT FUNCTION
VPD MODE (LOW VPD TRIGGER)
Pressing the up or down button sets the low VPD
trigger. Your heater will activate if the probe's
reading meets or falls below this threshold.
Once triggered, your heater will gradually ramp
up to the level set in ON Mode. If the probe's
reading falls below this trigger point, your heater
will gradually slow down to a stop or at the level
set in OFF Mode.
Set a trigger point to OFF if not in use, by holding
down the up and down button. If there is a level
set in OFF Mode other than zero, your heater will
run at that level when triggered to turn off.
