Ambiance

Ambiance thermostats are specified with a measurement accuracy of ±1°C at 20°C. This accuracy is consistent across the programmable, non-programmable, and RF models in the line. For process environments where temperature drift can affect equipment performance or product quality, this level of precision ensures that the controlled space remains within a tight tolerance around the setpoint. The accuracy is measured at a reference temperature of 20°C, which is typical for HVAC applications. When selecting a thermostat for a specific application, verify that the operating temperature range (0°C to 40°C for standard models, 7°C to 35°C for programmable models) aligns with your environmental conditions.

Ambiance thermostats have a switching capacity of 6(2)A at 230V. This rating indicates the maximum current the relay can handle for resistive loads (6A) and inductive loads (2A) at the specified voltage. This is a common rating for room thermostats used to control heating or cooling equipment such as boilers, pumps, or fan coil units. When integrating an Ambiance thermostat into a circuit, ensure that the connected load does not exceed these limits. For higher loads, an external contactor or relay may be required. The 6(2)A rating is printed on the product label and should be cross-checked with the electrical specifications of the equipment being controlled.

Ambiance thermostats are classified as Class IV energy efficiency with a 2% hysteresis. This classification is based on the European Energy-related Products (ErP) Directive, which sets standards for the energy performance of thermostats. Class IV indicates that the thermostat contributes to energy savings by maintaining a narrow temperature band around the setpoint, reducing unnecessary heating or cooling cycles. The 2% hysteresis means the thermostat switches on and off within a 2% deviation from the setpoint temperature, which helps prevent short cycling and improves system efficiency. This is particularly relevant for facilities aiming to meet energy management goals or comply with building regulations.

The Ambiance RF programmable thermostat operates at 868.35 MHz and has a transmission range of 200 meters in open air. This wireless capability allows the thermostat to communicate with remote sensors or actuators without the need for hard-wired connections. The RF model is powered by two AAA 1.5V lithium batteries, with a standby current of 20 µA, ensuring long battery life. The 868.35 MHz frequency is license-free in many regions, making it suitable for international deployment. The 200-meter range is sufficient for most commercial and industrial spaces, but physical obstructions such as walls or metal structures can reduce the effective range. For installations where the sensor is placed far from the thermostat, consider the layout and potential signal attenuation.

Ambiance thermostats are available in two temperature ranges depending on the model. Programmable models operate from 7°C to 35°C, which is suitable for typical heating and cooling applications where a comfortable or process-specific setpoint is required. Non-programmable and RF models operate from 0°C to 40°C, providing a wider window for environments that may experience lower or higher temperatures, such as storage areas or equipment rooms. When selecting a thermostat, ensure that the range covers your required setpoint and that the ambient conditions do not exceed the specified limits. The accuracy of ±1°C is maintained across the entire operating range, not just at the reference point.

Ambiance thermostats have a standby current consumption of 10 µA for non-programmable models and 20 µA for programmable and RF models. This low power draw is critical for battery-powered devices, as it directly affects battery life. With two AAA 1.5V lithium batteries, the typical battery life can extend to several years, depending on usage frequency and ambient conditions. The backlight, when activated, draws an additional 3–5 mA, but it is designed to turn off after a short period to conserve power. For installations in hard-to-reach locations, the low standby current minimizes the need for frequent battery replacements, reducing maintenance costs and downtime.
