Frequently asked questions
Common questions about Ambiance from 3G Electric.
What is the temperature measurement accuracy of Ambiance thermostats, and under what conditions is it rated?
Ambiance digital thermostats deliver ±1°C measurement accuracy when tested at 20°C ambient temperature. This specification applies across the full operating range (0°C to 40°C for standard models, 7°C to 35°C for RF programmable units). Accuracy remains within this tolerance in typical indoor installations; drift may occur if sensors are exposed to direct solar radiation or rapid air-movement artifacts.
Do Ambiance RF programmable thermostats require a hub or gateway to function?
The Ambiance RF programmable thermostat (SKU AMB05004) operates wirelessly at 868.35 MHz with a 200-meter transmission range and runs on two AAA lithium batteries. Product specifications do not indicate a central hub requirement; however, confirm installation topology with the manufacturer or our technical team, as control-system architecture varies by deployment model.
What is the standby power consumption for Ambiance thermostats, and how often must batteries be replaced?
Standby current draw is 10–20 µA depending on model (non-programmable units draw 10 µA; RF programmable draws 20 µA). Two AAA 1.5V lithium batteries power the device. Battery life depends on thermostat switching frequency and lighting use; in typical HVAC applications with moderate on/off cycles, expect 2–3 years of service. High-frequency switching or frequent backlight activation will shorten replacement intervals.
What is the switching capacity and voltage rating for Ambiance thermostats available?
All Ambiance thermostats in our catalog are rated 6(2)A at 220V or 230V AC. This capacity is suitable for standard HVAC contactor coils and heating/cooling relays. Verify compatibility with your load before installation; undersized or oversized loads may void warranty or create safety hazards.
Are Ambiance programmable and non-programmable thermostats interchangeable in HVAC installations?
Both programmable and non-programmable Ambiance models share identical electrical ratings (6(2)A, 220/230V) and form factors. Non-programmable units lock temperature setpoint, ideal for fixed applications. Programmable units allow weekly scheduling and multi-zone control. Compatibility depends on your control wiring and management requirements; consult system design documentation or our team for retrofit guidance.
What does Class IV, 2% energy rating mean for Ambiance thermostats?
Class IV, 2% indicates compliance with EU energy-labeling regulations (ErP Directive 2015/1186) for room thermostats. The 2% figure represents standby power loss as a percentage of rated heating capacity. This classification confirms the device meets low-standby-current requirements and supports building energy-efficiency certification schemes. It does not imply heating or cooling efficiency of the HVAC system itself.
