INSTALLATION

NOTE: The “Problems and Solutions” section at the end of this user’s guide will help you to correct your problems during the installation.

This thermostat has been designed to operate with any installation which has a RESISTIVE load not exceeding 5000W @ 347Vac such as electric baseboards, radiant ceilings and floors, electric convectors, etc. It is not compatible with a low voltage controller used by a central heating system or systems using a contactor or a relay whose current is under 1.8 Amps.

Electricians or experienced technicians should install the thermostat.

This thermostat is designed to be used with a self-protected heating system equipped with a thermal cut off and circuit breaker.

PARTS INCLUDED

One (1) TSSHC-3DP-237/277 Thermostat
Two (2) 6 32 screws 1 3/4 inches
Two (2) solderless connectors

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of thermostat clean and free from obstructions.

1) Connecting wires and mounting thermostat

Connect the rear thermostat wires to the power supply and to the electric Heater wires using solderless connectors for copper wires (there is no polarity for the wires). See schematic diagram.

Push the excess wire back into into the electrical box to prevent interference with the thermostat. Secure the thermostat using two (2) 6 32 screws 1 ¾ Inches long. Once the thermostat is properly installed, return power to heating system.

Note 1: All cables and connections must conform to the local electrical code.
Note 2: In normal use at full capacity (5000W), the housing temperature of the thermostat can reach 35 to 40 °C.
WARNING: Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.

2) Option selection

Some options have been factory set. Those default settings are:
The temperature is in °C, the heating control is proportional and the time format is 24 hours.

2.1 Temperature displayed in °C or °F

To change the temperature from °C to °F and back, maintain DAY button pressed down as RESET button is being pressed on and released. Then release DAY button

2.2 Time format displayed in 24 hours or 12 hours

To change the time format from 24 hours to 12 hours and back, maintain HOUR button pressed down as RESET button is being pressed on and released. Then release HOUR button.

2.3 proportional or ON/OFF heading control

This thermostat has been factory set to proportionally control electric baseboards, radiant systems and convectors. Since proportional control uses a fast commutation rate, it is not compatible with fan equipped systems (see characteristics). Also, this control mode occasionally create light flickering, especially in rural area.

You can change the control mode to make it compatible with fan equipped systems or to eliminate the light flickering.

To do so, maintain MIN button pressed down as RESET button is being pressed on and released. Then release MIN button. Following this operation, the display will show the FAN indicator. To return to proportional control , repeat the same operation.

3) Memory backup

In the event of a power failure, an internal circuit will maintain the programming. The display will stay on for 15 minutes; beyond this period, the display will turn off. An indicator “LP” will be shown on the display. Only the time will have to be set if power failure is more than ten hours. The thermostat will return to the same operation mode as set before the power failure.

4) First power up

When power is applied for the first time, the display must show the day and hour as follows:
0:00 MO (Monday)

The active operation mode is the framed MAN mode, the setpoint is 20°C and the ambient temperature a displayed. It if the display is different, maintain PGM button pressed down as RESET button is being pressed on and released. Then release PGM button.

750 WATTS INSTALLATION ONLY

During the 30 minute period following the installation or a long power failure (more than 10 hours), the light intensity of the display decreases when a button is pressed on while the thermostat is in heat mode. This problem will disappear when the accumulator for the memory backup will be charged.

OPERATING MODES

The TSSHC 3DP 347/277 thermostat has three (3) operating modes:
AUTO, MAN and ECONO.

They are selected though the MODE button. On display, the active mode is framed. The frame moves on to the next mode each time the MODE button is pressed on.

The AUTOmatic mode runs in sequence (hourly) the programs recorded by the user.
Pressing on the ▲ or ▼ displays the temperature setting and the SETPOINT indicator for five (5) seconds.

To see the weekday and weekend programs, select the AUTO mode and press successively on PGM button to see the programs appear on the display.

The MAN mode allows the user to override the programming.

The first time the ▲ or ▼ is pressed on, the temperature is setting is displayed. For all subsequent times pressed on, the temperature setting will change 1°C.

The ECONO mode has two (2) programs in which the day, the time, and the setpoint has to be programmed. For instance, this operating mode can be used for a cottage installation where the user goes only on weekends.
Program 1: Friday 3:00 PM, 21°C
Program 2: Friday 8:00 PM, 15°C

The temperature will be maintained at 21°C Friday from 3:00 PM to 8:00 PM, and maintained at 15°C the rest of the week,

This gives you a comfortable temperature at your arrival and if you are not going to your cottage for the weekend, there will be only a minimal heating period.

To see the ECONO programs, select the ECONO operating mode and press on PGM button successively to see programs 1 and 2 appear on the display. In ECONO mode, pressing on the ▲ or ▼ displays the temperature setting.

CHARACTERISTICS

1) Proportional and on/off controls
This thermostat works differently than the conventional electro-mechanic one. The latter can have a differential of temperature up to 4°C while this electronic thermostat has one of only 0.4°C This slight oscillation eliminates the discomfort often found with conventional electro-mechanic thermostats.

The proportional controller determines the amount of power required by the electric heating system to maintain the exact ambient temperature of the temperature setting.

To see this process, the display shows, in real time, the percentage of power applied to the electric heating system.

If you have programmed the heating control to ON/OFF to control a ran equipped system, the display will show the fan indicator and 100% when the heating system will turn ON and 0% when it will turn OFF. In this case, the temperature regulation will be ±0.5°C around the setpoint.
