Bravo Tstat 2 ON/OFF Thermostat
DESCRIPTION
7S7$7 2 series on/off thermostat is mainly used in the central air-conditioning heating and cooling system. It works with a TSC series temperature sensor. It provides temperature control for central air-conditioning fan coil cooling/heating motorized valve or another electric actuator by the control signal which is produced by comparison of actual tested ambient temperature and set temperature.
CHARACTERISTICS
- Power surge and instant pulse protection.
- LCD showing ambient temperature, state and air volume.
- With system switch and fan speed switch.
- Built-in or external long-distance temperature-sensitive element (NTC thermistor).
- With ABS fireproof plastic, in compliance with UL-94V0 standards.
- With flexible installation and convenient wiring.

INSTRUCTION
- Cool/heat shift: When the thermostat is used for the 2-pipe application, move the power supply switch to “”, the system will enter into a cooling state, the LCD will show the cooling state symbol “”. Move the switch to “”, the system will enter into a heating state, the LCD will show the heating state symbol “”.
- Move the switch to “”, the LCD will be shut off, and then the system will be shut off, too. When it is used for the 4-pipe application, move the power supply switch to the “ON” position, the system will be powered on and start to work, the cool/heat state will shift automatically according to the ambient temperature and setting temperature, and output control signal to control the corresponding actuator. Move the power supply switch to the “OFF” position, the LCD will be shut off and then the system will be shut off, too.
- Built-in/external sensor: When a built-in NTC thermistor is used, the jumper J3 should be put to the “Int” position. If the external NTC sensor is used, the wire of the external sensor should be connected with terminal Rx, and the jumper J3 should be put to the “Ext” position.
- Fan: When the thermostat is in a cooling or heating state, move the fan switch , and the LCD will display the corresponding air volume symbol. The terminals will output power and provide an operating power supply for the fan. If the thermostat isn’t connected to the fan, only can be shown on the LCD. The symbol can only be shown when the thermostat is connected to the fan completely and correctly.
- Temperature setting: When the user presses △the （increase）/ ▽（decrease）button, the LCD display temperature setting will show an increase or decrease accordingly (The default value is 25 / ℃ 77 oF). For centigrade calculation, the increase/decrease rate is 1℃, the adjusting range is 10~30℃; for Fahrenheit calculation, the increase/decrease rate is 1 oF, the adjusting range is 50~86 oF. When the user stops pressing the button for over 5 seconds, the thermostat will change the setting temperature data in its memory, and save the updating data. The LCD will show the ambient temperature. (You can choose the initialization setting point as 22℃/72℉, 23 / ℃ 74℉ or 25 / ℃ 77 ℉.)
- The temperature range shown on the LCD is 0 ~ ℃ 40 or 32 ℃ ℉ ~ 99 ℉.
