CT1950B - DPST; Makes heating circuit on temperature fall. Breaks both sides of 240 volt line with switch in "OFF" position. Operating range: -20 to +104°F [-30 to +40°C], 5 to 95% RH, non-condensing. CONTROL RANGE: 7 to 27°C [45 to 80°F] in 1° increments. Factory set at 16°C [61°F] . SWITCHING: Patented CoolSwitch™ thyristor with relay conductor. WIRING CONNECTIONS: 6" [150 mm] stranded copper leadwires suitable for connection to aluminum wiring if approved special service CO/ALR connectors are used. ELECTRICAL RATINGS, NON-INDUCTIVE: 16 A (3800W) maximum, 2 A (500W) minimum @ 240V, 60 Hz. (12 ft. of baseboard maximum) SENSING ELEMENT: Electronic thermistor. 2 INSTALLATION ! WARNING • This thermostat is a line voltage (240 Vac) control. Do not install it unless you are completely familiar and competent with house wiring. If improperly handled, there can be a risk of 240 Volt electric shock hazard which may cause serious injury or death. • The CT1950/CT1957 is rated for normal full load current on a dual residential 20 A circuit breaker or fuse block. Do not use on circuits protected by higher-rated over-current protection devices. Some sustained fault conditions can cause product failure. • Do NOT connect to voltage different from device rating. ! CAUTION • Disconnect power supply before making wiring connections to prevent electrical shock or equipment damage. • All wiring must comply with applicable codes and ordinances. • Thermostats are designed to be used with appliances having a limit control. • Maximum load for thermostat must not exceed 3800W, otherwise a potential fire hazard exists. (ie. greater than 12 ft. of baseboard) LOCATION: Install a vertical switch box for mounting the CT1950/CT1957 approximately 1.5 m (5 ft.) above the floor on an inside wall where the thermostat will be subjected to average room temperature. The thermostat must be placed away from concealed warm or cold water pipes, air ducts, or drafts from hallways, fireplaces or stairways to sense temperature properly. Do not place thermostat above heater. 3 WIRING: 1. Disconnect power while installing. Double check that thermostat is rated for voltage and amperage of load to be controlled. 2. Remove cover as needed by carefully prying at the top or bottom edge with a coin or slot screwdriver. Fig. 1 Wiring 1 Power supply. Provide disconnect means (22) CT1950A/ and overload protection as required. 2 Special service CO/ALR solderless connections must be used when connecting aluminum conductors; otherwise, a fire hazard may result. 3 Thermostat breaks heating circuit on (11) CT1957A temperature rise. 4 Thermostat is designed to be used with appliances equipped with a limit control. 5 B Model thermostat breaks both sides of line with switch in OFF position L1 T1 L1 L1 ELECTRIC HEATER L2 1 2 4 3 CT1950A/ L1 T1 ELECTRIC HEATER 2 4 3 RED 5 L2 RED T2 BLACK BLACK BLACK 1 CT1950B BLACK (A) (B) L2 4 WIRING cont’d 3. When replacing an old line voltage wall thermostat, remove it carefully to avoid damage to the insulation on the wiring. Check the old insulation for cracks, nicks, or fraying and apply certified electrical tape where necessary to achieve adequate insulation, or replace the wires in an approved fashion. 4. Attach wires with solderless wire connectors approved for the size and number of wires to be connected. Be sure that all wire connec...
