OPERATION
The o er-limit and low-limit temperatures are used in conjunction
with the on-board indicator lights and/or remote alarms to indicate
a fault situation. If the o er-limit temperature is reached, power to
all elements will be shut off.
To set temperatures:
1 Press the Scroll button one or more times until the desired function setting LED is lit
The LCD display now indicates the current function setting
2 Use the Land Mbuttons to set the temperature higher or lower than the current setting
See the following section, Operating Temperatures, for a list of acceptable temperatures
3 Press the Scroll button one or more times to either highlight another function or until all func-
tion lights are out, which returns the control unit to operating mode

When programming the con-
