SETTING THE EVENT TIMES & TEMPERATURES
The HP75 can be set by the installer to provide either 2 or 6 events
each day. Refer to the installer setting instructions if this parameter
needs to be altered. Please note that for simplicity the diagrams in this
setting instruction assume that the unit has been set in the “6 events
per day” mode.
The first event (time and temperature) is displayed, together with the
day or days when it is active. Note that the day number(s) displayed
will be that of the current day. In 7 Day mode only a single day number
will be displayed, in 5/2 Day mode either 12345 or 67 will be displayed.
