aube CT240 Telephone Controller Installation Guide

Introduction

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 auxiliary 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.

Installation

Any device connected to a telephone line must conform to the country’s standards. The CT240 telephone controller meets:

• FCC68 standards for installation on the North American network.
• FDTBR21 standards for installation on the European network.

Include Parts

• 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 answering machine switch to ON before installing the CT240.
Make sure that your answering machine answers after a minimum of 4 rings.

Figure 3 : Typical Installation

1. 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 electrical box.

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

3. 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.

4. Connect the thermostat and load. Both outputs work simultaneously.
   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 Vacation 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 Vacation setpoint, use the 123 output (FIGURE 5) :

   • Load = terminals 2 and 3 (NC) (open = Vacation)

   • Thermostat = terminals 1 and 2 (NO) (closed = Vacation)

5.  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.
