פּראָדוקט פֿעיִקייטן
The Suuwer S725 thermostat offers a range of features designed for efficient home climate control:
- סיסטעם קאַמפּאַטאַבילאַטי: Designed for Heat Pump systems (with or without auxiliary/emergency heat) and most 24V conventional single-stage systems (gas, oil, electric furnaces) up to 2 Heat and 1 Cool.
- פּראָגראַממאַביליטי: 5-1-1 Day Programmable with separate programs for weekdays and weekends, featuring 4 program periods per day (Wake, Leave, Return, Sleep).
- ווייַז: 4.5 sq. inch large LCD display with a white backlight, simultaneously showing room temperature, set temperature, and current time.
- פאָכער קאָנטראָל: ווענטילאַטאָר שליסל מיט אָן און אויטאָ פונקציעס.
- מאַכט אָפּציעס: Dual powered by 24VAC or 2 AAA batteries. No common wire (C-wire) required on most systems (required for heat-only and cool-only systems).
- טעמפּעראַטור קאָנטראָל: Separate heating and cooling swing (cycle rate) adjustable from 0.2°F to 2°F.
- קאַמפּרעסער פּראַטעקשאַן: 5-minute compressor delay protection (selectable ON or OFF).
- ינדיקאַטאָרס: Low battery indicator and air filter change indicator (selectable ON or OFF, settable from 50-2000 hours).

- ווייַז אָפּציעס: Fahrenheit or Celsius temperature display, 12 or 24-hour clock.
- טערמינאַל באַצייכענונג: RH, G, Y, C, O, B, E, W2.
קאַמפּאַטאַבילאַטי
The Suuwer S725 thermostat is compatible with the following HVAC systems:
- Heat Pump systems (with auxiliary or emergency heat)
- Heat Pump systems (without auxiliary heat)
- Most 24V conventional single-stage systems (e.g., conventional forced air, central gas, oil, or electric furnaces) up to 2 Heat and 1 Cool.
נישט-קאמפאטיבלע סיסטעמען:
- 110-240V electric heat systems (e.g., electric baseboard heat, line voltage, convectors, radiant-ceiling heat).
- Conventional multi-stagE סיסטעמען.
- Mini-split systems.
- 12V RV thermostats.
Before installation, verify your existing system's compatibility. If your current thermostat has stranded wires or is labeled 110V or 120V, it is not compatible with this thermostat.

סעטאַפּ & ייַנמאָנטירונג
זיכערקייַט פּריקאָשאַנז:
- Turn off power to the heating/cooling system at the main fuse or circuit breaker panel before beginning installation.
- Ensure all wiring is performed by a qualified individual if you are unsure.
Removing Your Old Thermostat:
- Turn off the power to your heating and cooling system at the circuit breaker.
- אַראָפּנעמען די דעקל פון דיין אַלט טערמאַסטאַט.
- Take a picture of the wiring connections for reference.
- Label each wire with the provided cable labels according to its terminal designation.
- Disconnect the wires and remove the old thermostat's mounting base.
אינסטאַלירן דעם נייעם טערמאָסטאַט:
- Position the new thermostat's sub-base on the wall where the old thermostat was located.
- צייכן די מאַונטינג האָלעס.
- Drill pilot holes if necessary and insert the wall anchors.
- Feed the wires through the opening in the sub-base.
- Secure the sub-base to the wall using the provided screws.
וויירינג קאַנעקשאַנז:
Connect the labeled wires to the corresponding terminals on the Suuwer S725 thermostat's sub-base. Refer to the wiring diagrams below for common system types.
