Step 2: mount the Sensaphone 400.
Choose a location for your Sensaphone that allows for easy wiring to the
thermostat, such as near your heater/air conditioning system. Mount the
unit on a wall or flat on a desktop or table surface. Plug in the power sup-
ply and connect the telephone line.
Step 3: Connect cable from thermostat to Sensaphone 400.
This Sensaphone 400 has a terminal strip below the input/output wiring
door that will connect to the 12VDC power supply and X & C terminals
of the thermostat (See Figure 1). This connection is required to switch the
thermostat between normal and vacation modes. Run a two-conductor
cable from the thermostat to the Model 400. On the thermostat, connect
the red wire to the X (+) terminal, and the black wire to the C (-) terminal.
On the 400, connect the red wire to the NO terminal. Connect the black
wire to the negative wire from the power supply. Use a wire nut to complete
this connection. Connect the positive wire from the power supply to the
“C” terminal on the model 400.
