Since proportional control uses a fast commutation rate, it is not compatible with fan equipped systems (see characteristics). Also, this control mode could 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. An indicator "LP" will be shown on the display. Beyond this period, the display will turn off. Only the time will have to be set if power failure is more than six hours. The thermostat will return to the same operation mode as set before the power failure. ECONO 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, 20 °C Program 2: Friday 8:00 PM, 15 °C The temperature will be maintained at 20 °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. 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 temperature setpoint is 20 °C and the ambiant temperature is displayed. If the display is different, maintain PGM button pressed down as RESET button is being pressed and released. Then release PGM button. 500 WATTS OR LESS INSTALLATION During the 30 minute period following the installation or a long power failure (more than 6 hours), the light intensity of the display decreases when a button is pressed on while the thermostat is in the heat mode. This problem will disappear when the accumulator for the memory backup will be charged. OPERATING MODES The TH102D thermostat has three (3) operating modes: AUTO, MAN and ECONO. They are selected through 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. AUTO 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. MAN The MAN mode allows the user to override the programming. The first time the or is pressed on, the tempera ture setting is displayed. For all subsequent times pressed on, the temperature setting will change 1 °C. PROGRAMMING 1) Adjustment of time and day Example of setting: Thursday 8:15 AM Use DAY, HOUR and MIN buttons to set the time. Once set, press on RET button to exit the time and day adjustment mode Note 1 : Time indicator is showing you that the time must be set. Note 2 : The thermostat has an automatic return. When such functions as time recording, programs recording, etc., are not completed by pressing on RET button, the thermostat will automatically exit the mode after 60 seconds. 2) Typical suggested programs This thermostat can store up to four (4) daily programs for weekdays and four (4) daily programs for the weekend. Also, there is two (2) programs for the ECONO mode. To practice programming use the following example.

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 0.3 °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 con trol to ON/OFF to control a fan equipped system, the display will show the fan indi cator 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. 2) Characteristics • Model: TH102D • Electronic programmable line voltage thermostat (2 wires non polarized) • Supply: 120/240 VAC, 50/60 Hertz • Load: 10.4 A maximum, 1.0 A minimum (Resistive only) • Power: 2500 W @ 240 VAC or 1250 W @ 120 VAC • Power consumption (off): 860 mW • Approvals: CSA / UL • Display range: 0 to 99 °C (0 to 99 °F) • Setting range: 5 to 27 °C (40 to 80 °F) • Storage: -20 to 50 °C (-4 to 120 °F) • Temperature regulation: 0.3 °C (proportional), +/- 0.5 °C (ON/OFF) • Precision: ± 0.5 °C (2500 W) of temperature setting • 10 programs: 4 weekday programs, 4 weekend programs and 2 ECONO programs NOTE : In normal use at full capacity (2500 W), the housing temperature of the thermostat can reach 35 to 40 °C. 720-102002-A 3/4 WARRANTY AUBE TECHNOLOGIES INC.
