Aube CT240 - Manual

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.

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.

o

OPTIONAL. Connect your phone (or answering machine) to the
PHONE connector of the CT240.

p

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.

q

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)

r

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

is ON when

the circuit is powered.
