Boost Heater Mode
A boost heater is activated by the front panel "Boost Heater" switch. The
switch must be on for either user mode to function. It may be operated in either
automatic or manual user modes. The default is automatic (auto). The auto
mode will cause the boost heater to come on automatically if the set-point is in-
creased to 5°C above the new current bath temperature..
When the manual user mode is selected, the front panel boost heater switch al-
lows the user to manually turn the boost heater on and off regardless of temper-
ature. The heater is powered through the same circuit as the control heater and
will cycle on and off when the set point is reached. Normally, it is best to turn
off the boost heater when the controller is controlling.
The heater mode may be selected in the parameters menu.
