Set Thermostat Mini-Jumper - Honeywell T7200 Manual

SET THERMOSTAT MINI-JUMPER

NOTE: This operation must be done prior to installing the
batteries. If batteries are installed prior to this operation,
remove battery for 15 minutes and begin.
The T7300 is factory-set for conventional system con-
trol using the Q7300A,B,E,G. If using with a heat pump
and Q7300C,D,F, locate the mini-jumper on the back of the
T7300. See Fig. 14. Pull the mini-jumper off the two
CONV pins and move to the two HEAT PUMP pins. This
changes the thermostat to the heat pump algorithm.
If you wish to change the control of the thermostat
because a new subbase has been purchased, remove battery
for 15 minutes, change mini-jumper position, and re-install
battery.
