Podešavanje i instalacija
Sigurnosne mjere:
- 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.
- Skinite poklopac starog termostata.
- Uslikajte spojeve ožičenja kao referencu.
- Label each wire with the provided cable labels according to its terminal designation.
- Disconnect the wires and remove the old thermostat's mounting base.
Montiranje novog termostata:
- Position the new thermostat's sub-base on the wall where the old thermostat was located.
- Označite montažne rupe.
- Drill pilot holes if necessary and insert the wall anchors.
- Feed the wires through the opening in the sub-base.
- Pričvrstite podnožje na zid pomoću priloženih vijaka.
Ožičenje:
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.
| Terminal | Function (Heat Pump System) | Function (Conventional System) |
|---|---|---|
| R | Transformer Power | Transformer Power |
| C | Transformer Common (Optional 24 VAC common connection when thermostat is used in battery power mode) | Transformer Common |
| B | Preklopni ventil pod naponom u HEAT | N/A |
| O | Preklopni ventil pod naponom u HLAĐENJU | N/A |
| G | Relej ventilatora | Relej ventilatora |
| W/E | Prvo Stage od Hitnog GRIJANJA | Prvo Stage od HEAT |
| W2 | Drugi Stage od GREJANJE/HITNO GRIJANJE | Drugi Stage od HEAT |
| Y | Prvo Stage od HEAT i COOL | Prvo Stage od COOL |
Napomena: Use either O or B terminals for the changeover valve, but not both. In many systems with no emergency heat relay, a jumper can be used between E and W2.

Rješavanje problema
Ako imate problema s termostatom, pogledajte sljedeće uobičajene probleme i rješenja:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| No display or blank screen. | Nema struje ili su baterije prazne. | Check circuit breaker. Replace AAA batteries if running on battery power. Ensure 24VAC power is connected if not using batteries. |
| Sistem grijanja/hlađenja ne reaguje. | Incorrect wiring, system switch in OFF position, or compressor delay. | Verify wiring connections. Ensure SYSTEM switch is set to HEAT or COOL. Wait 5 minutes for compressor delay protection to cycle. |
| Temperatura netačna. | Lokacija termostata, potrebna kalibracija. | Ensure thermostat is not in direct sunlight or near heat sources. Perform room temperature calibration adjustment (refer to advanced settings). |
| Thermostat runs AC when set to HEAT (or vice-versa). | Incorrect wiring of O/B terminals or system configuration. | Verify O/B wire connections. Check technical settings for correct system type (Heat Pump vs. Conventional) and O/B valve operation. |
| Fan not operating correctly. | Fan switch setting. | Ensure FAN switch is set to ON for continuous operation or AUTO for operation with heating/cooling cycles. |
If problems persist after attempting these solutions, contact customer support for further assistance.
