Avansa 2007 TX

Product detailed description

The Avansa 2007 TX wireless thermostat is suitable for installation in residential, commercial and industrial buildings with central heating or cooling systems. This programmable thermostat is commonly used in systems with gas boilers, heat pumps or air conditioning units that require wireless temperature control. The device is particularly useful in retrofit projects where running new cables is impractical, and in buildings where optimal thermostat placement may change over time. The 50m signal range allows flexible installation while maintaining reliable communication between the transmitter and receiver units.

Typical applications include individual rooms requiring independent climate control, as well as larger systems where multiple zones need separate regulation. The thermostat supports both radiator heating systems and underfloor heating systems, with different sensitivity settings for each type of installation. The device's programmable weekly schedule allows for six different temperature settings per day, with 10-minute time increments and 0.5°C temperature resolution.

The 6A load capacity and 250V AC compatibility make this thermostat suitable for most central heating systems. The 50m signal range is effective in open spaces but may be reduced in buildings with metal structures or reinforced concrete walls. The IP30 rating indicates protection against solid objects larger than 2.5mm but no protection against water, so installation should avoid areas with potential moisture exposure. The NTC 10KΩ temperature sensor provides accurate readings within the 0-35°C operating range.Installation and connection The installation process involves mounting the thermostat unit in a suitable location away from direct sunlight and heat sources, and connecting the receiver unit to the heating system control circuit. The receiver requires 230V AC power supply at 50Hz. The thermostat operates on two LR6 (AA) batteries, which should be installed according to the polarity markings. When connecting to a boiler, ensure the system has a double-wire connection point for room thermostats. Common installation mistakes include placing the thermostat near windows or doors where temperature fluctuations are extreme, and failing to account for signal obstructions in multi-storey buildings. Always verify that the thermostat and receiver are operating on the same frequency and security code.

Compatibility and accessories

The Avansa 2007 TX is compatible with most gas boilers and HVAC systems that accept 24V-250V AC control signals. For additional functionality, it can be combined with the Avansa TX plug-in module to control 230V electrical devices such as circulation pumps or electric heaters. The system requires both the transmitter and receiver units to function. When installing in complex systems with multiple zones, additional receiver units may be needed for each controlled zone. The thermostat's programmable features make it suitable for use with both traditional radiator systems and modern underfloor heating installations.

Technical background for designers

The thermostat operates using radio frequency communication between the transmitter and receiver units, eliminating the need for physical wiring between the control device and the heating system. The NTC 10KΩ temperature sensor provides resistance changes proportional to temperature variations, which are converted into digital readings by the thermostat's internal electronics. The system's design allows for flexible installation without compromising control accuracy. The 0.5°C measurement accuracy and ±0.2°C switching sensitivity ensure precise temperature regulation while minimizing unnecessary system cycling. The device's low power consumption (1.3mW) and battery operation make it suitable for installations where permanent electrical connections are not feasible.

Service and operation

The thermostat requires minimal maintenance, primarily consisting of periodic battery replacement when the low battery indicator appears. The device should be kept clean to ensure proper sensor operation. In the event of power interruption to the receiver unit, the system will automatically pause operation until power is restored. The built-in pump protection function activates daily at 12:00, running the heating system for one minute if it has been inactive for more than 24 hours. This prevents pump clogging in systems with infrequent operation. No scheduled service intervals are required beyond basic visual inspections and battery replacements.

Frequently asked questions

Can the Avansa 2007 TX be used with underfloor heating systems?
Yes, the thermostat has specific sensitivity settings for underfloor heating (0/-0.2°C) which differ from standard radiator heating settings (±0.2°C). This allows for optimized temperature control in different heating system types.

How does the thermostat handle power outages?
In the event of a power interruption to the receiver unit, the heating system operation will pause. Once power is restored, the system resumes according to the programmed schedule. The transmitter unit continues to operate on battery power during outages.

Can multiple thermostats be used in one building?
Yes, multiple Avansa 2007 TX units can be installed in different zones of a building. Each thermostat must be paired with its own receiver unit for independent zone control. The units operate on individual security codes to prevent interference between different systems.

What is the maximum load capacity of the system?
The thermostat supports a maximum load of 6A for resistive loads and 2A for inductive loads. This makes it suitable for most standard central heating systems but may require additional relays for higher capacity applications.
