The CT240 telephone controller is designed to remotely control your
home's thermostat. It is possible to command a temperature
decrease (Unoccupied) during a prolonged absence or a temperature
increase (Comfort) before you return home.
Depending on your thermostat's operating characteristics, it either
connects to the Aube output (for most Aube models) or to the auxil-
iary output.
When the auxiliary output is not used to control a thermostat, it can
be used to simultaneously control a load such as a water heater,
lighting, etc.

Any device connected to a telephone line must conform to the coun-
try's standards. The CT240 telephone controller meets:
• FCC68 standards for installation on the North American network.
• FDTBR21 standards for installation on the European network.
• One CT240 telephone controller
• One power transformer 120 V (North America) or 250 V (Europe)
• One 5 m (16 foot) telephone cable
NOTE:
If you are using an answering machine, position the answer-
ing machine switch to ON before installing the CT240.
Make sure that your answering machine answers after a minimum of
4 rings.
Mount the CT240 near a telephone outlet.
NOTE:
If you plan to connect a load having more that 30 volts on the
auxiliary output, the CT240 must be installed inside a certified electri-
cal box.
OPTIONAL. Connect your phone (or answering machine) to the
PHONE connector of the CT240.
Connect one end of the telephone cable to the LINE connector of
the CT240 and the other end to the telephone outlet in your
home.
Connect the thermostat and load. Both outputs work simulta-
neously.
NOTE:
Refer to your thermostat's electrical specifications (telephone
interface) for the connection requirements.
• If your thermostat requires a 12 VDC signal to switch to Vaca-
tion setpoint, use the ABC output (FIGURE 4):
A and C terminals:
• 0 VDC in Comfort mode
• 12 VDC in Vacation mode
NOTE:
50 mA max. for parallel connection of Aube thermostats.
• If your thermostat requires a dry contact to switch to the Vaca-
tion setpoint, use the 123 output (FIGURE 5):
• Load = terminals 2 and 3 (NC) (open = Vacation)
• Thermostat = terminals 1 and 2 (NO) (closed = Vacation)
When all connections have been made, connect the power
transformer to the 9 V outlet of the CT240 and the other end to
the wall electrical outlet. The power indicator light
