The blower can be further controlled by installing an external wall switch or line voltage thermostat. This will
allow manual on/off control of the blower from a more convenient location or automatic on/off control based on
room temperature.
This can be done by replacing the jumper wire between terminals #3 and #4 on the control block terminal strip
(inside lower junction box) with a line voltage circuit.
