Ultimate convenience - control your thermostat plus three other household devices from a touchtone phone. The CT241-01 Telephone controller has four universal relay outputs (dry contact). Each output operates independently. It connects directly to existing phone lines and is password protected. LEDs show the output status. It can be activated by home/cell phones and is compatible with answering machines. It allows the user to switch from one mode to another (for TH115 series thermostats) or to turn an electric appliance on or off.
Item # CT241-01
The CT241 telephone controller is designed to remotely control up to four independent loads. For example, you could connect a sprinkler system, indoor/outdoor lights, etc. Another example would be to connect an output to the thermostat’s phone interface (which requires a dry contact) to switch from Comfort mode to Vacation mode and vice versa. Loads can be activated or deactivated remotely (by telephone) or manually (on-site).

standards. The CT241 telephone controller meets:
• FCC68 standards for installation on the North American network.
• FDTBR21 standards for installation on the European network.
2.1 Included Parts
• One CT241 telephone controller
• One power transformer 120 V (North America) or 250 V (Europe)
• One 5 m (16 foot) telephone cable
2.2 Installation Procedure
NOTE: If you are using an answering machine, position the answering
machine switch to ON before installing the CT241. Make sure that
your answering machine answers after a minimum of 4 rings.
Figure 3: Typical Installation: 1. Mount the CT241 near a telephone outlet.
NOTE: If you plan to connect a load having more that 30 volts on the
auxiliary outputs, the CT241 must be installed inside a certified electrical
box.
2. OPTIONAL. Connect your phone (or answering machine) to the
PHONE connector of the CT241.
3. Connect one end of the telephone cable to the LINE connector of
the CT241 and the other end to the telephone outlet in your
home.
4. Connect the loads.
The four outputs of the CT241 allow you, for example, to activate
or deactivate the lighting system, the sprinkler system, the water
heater, etc.
You can also connect a thermostat’s telephone interface (which
requires a dry contact) to automatically switch from Comfort
mode to Vacation mode and vice versa.
NOTE: The capacity per output is 10 A @ 240 VAC. However, to
avoid electrical shocks, the direct connection of a load exceeding
30 VAC is not permitted unless the CT241 is installed inside a certified
electrical box.
5. When all connections have been made, connect the power
transformer to the 9 V outlet of the CT241 and the other end to
the wall electrical outlet.
The power indicator light is ON when the circuit is powered.
