************************************************* TA652FC-W -- 2 pipe Fan Coil Wi-Fi Thermostat ************************************************* .. CAUTION:: 1. Turn off all electrical devices (e.g. heater, cooler) that are connected to the unit before installation and maintenance. 2. The installer must be a trained service personnel. 3. Disconnect the power supply before maintenance. 4. It must be mounted on a dry clean indoor place. 5. Do not expose this unit to moisture. 6. Do not expose this unit to dipping or splashing. Introduction ============= TA652FC-W is a controller that controls fan coil system to maintain room temperature at a desired level. Changeover sensor is required to install when auto changeover is used. Feature List ============= * Voltage supply: 230Vac * Temperature display in °C or °F * Temperature measurable range : 0 - 50 °C * 2-pipe system * Manual changeover or Auto changeover can be selected * Selection of Heat/Cool * 7days/5+1+1days, 1day program, no program. * EEPROM stores all settings * Adjustable control span Wiring ======= **NOTE:** Power supply of TA652FC-W is 230Vac. .. table:: :widths: auto =========== ================ Terminals Device =========== ================ L 230Vac Live N 230Vac Neutral Qv Changeover valve Q1 Fan Low Q2 Fan Med Q3 Fan High T1 Floor Sensor T2 Floor Sensor =========== ================ Pull all cables back into the wall beforehand to avoid trapping of wires.

When the thermostat is Off. No Output will be activated. Clock setting ------------- **Normally the clock is automatically set once Wi-Fi is connected and synchronize for each day. So manual set is not necessary when it is online.** * Press |icon_clock| to start the setting * Press |icon_up| / |icon_down| to change the day of week * Press |icon_clock| again to confirm day of week setting and start to adjust hour * Press |icon_up| / |icon_down| to change the hour * Press |icon_clock| again to confirm hour setting and start to adjust minutes * Press |icon_up| / |icon_down| to change the minutes * Press |icon_clock| again to confirm minutes setting and start to adjust day of week * Press |icon_blank| to confirm or leave the clock setting. Or return after no key pressed for 20 seconds. Clock synchronization ^^^^^^^^^^^^^^^^^^^^^^ When Wi-Fi is connected and time synchronization is need. Please use the App for time synchronization. Schedule Programming --------------------- When **1 day** / **5+1+1 day** / **7day program** is selected in internal setting. * Hold |icon_clock| to start the setting. * Press |icon_up| / |icon_down| to adjust the day of week * Press |icon_clock| to confirm. * Press |icon_up| / |icon_down| to adjust the time of schedule * Press |icon_clock| to confirm. * Press |icon_up| / |icon_down| to adjust the setpoint * Press |icon_clock| to confirm. * Press |icon_blank| to confirm return. Override Temperature --------------------- The Set point can be adjusted by |icon_up| / |icon_down|. When it is in program mode, the set point will be overwritten until the next time slot. |icon_clock| can be pressed to release the override status.
