Avansa 2007 TX

Avansa 2007 TX - programmable weekly wireless thermostat 

The wireless thermostat Avansa 2007 TX is suitable for controlling most boilers. The thermostat can be connected to any gas boiler equipped with a two-wire room thermostat connection. The device can also be connected to an air conditioning unit regardless of whether the unit operates at 24V or 230V. The device can be programmed according to your needs so that the heating (cooling) system starts at the time and to the temperature you require. Besides ensuring comfort, it also helps reduce energy costs. You can set 6 different thermostat on-times (in 10-minute increments) for each day, with a freely adjustable temperature (in 0.5°C increments) for each of the six on-times.  The device consists of two units: one portable control unit (the thermostat) and one receiver unit, which is used to control the boiler. The connection between the thermostat and the receiver is made via radio frequency waves, so there is no need to run wiring between the thermostat and the boiler. Both units are factory pre-set to operate on the same frequency.  The thermostat and receiver each have their own security code. For this reason, unknown external radio frequency signals cannot disrupt the safe operation of the device. 

The portability of the thermostat has the following advantages:

• there is no need to run wiring, which is especially advantageous when renovating old buildings,
• the optimal location for the thermostat can be chosen while in use,
• using the thermostat is also suitable in cases where you want to use the device in different rooms at different times of the day

The sensor built into the thermostat has a range of approx. 50 m in open space. This distance can be significantly reduced within a building, especially where iron structures or reinforced concrete walls come between the radio waves. The selectable switching sensitivity is ± 0.2 °C (the manufacturer's recommended basic setting for radiator heating) or +0/-0.2 °C (recommended setting for underfloor heating). These values refer to the temperature difference between the set temperature and the actually measured room temperature at the moment the thermostat switches on. For example, with the manufacturer's basic setting of 20 °C, the device switches the boiler on when the temperature reaches 19.8 °C or lower, and switches the boiler off when it reaches 20.2 °C or higher. If needed, the thermostat can also be extended with an Avansa TX socket, which allows you (without any installation work) to control any electrical device with an operating voltage of 230V (e.g. boiler, pump, heat radiator..). The thermostat is equipped with a pump protection function. This function is used to prevent the pump from seizing up. The device switches the boiler on every day at 12:00 for one minute, if the boiler  has not been switched on according to the program for more than 24 hours. If, for any reason (e.g. a power outage), the power supply to the receiver is interrupted, boiler operation is also suspended.
