Setting a Thermostat Jumper for
Programmable Output Operation
To control one of the MISC outputs using time, temperature, or
phone based operation, place the MISC1, or MISC2, or MISC3
MISC3 jumper on the terminal labeled PROG (see diagram below).
This extra output will supply 24VAC to the selected MISC terminal
based on the programming described in the following pages. Only
one of the three outputs (MISC1, MISC2, or MISC3) is required to
have this jumper. For more information regarding the MISC1, MISC2,
and MISC3 outputs, please see section 21.
In the diagram below, the MISC1 jumper has
been set for PROG operation.
