Room RF thermostat BT-D02-RF

Electronic thermostat with radio frequency back-lit LCD display (868 MHz) designed to control different types of heating and cooling** systems. Temperature control is based on internal sensors. An external sensor (PPLELE06019) can be connected without any additional external power supply. A LED indicates whether the heating switch-on signal is activated. Operating temperature: 0÷50°C. Electrical protection Class II. Temperature control range: 5÷37°C. Control characteristics: proportional band (PWM 2°C for 10min/cycle). Power supply 2 AAA LR03 1.5V Alkaline. Life ~2 years. Sensor: internal and/or external (opt.) NTC 10kW at 25°C. Radio frequency 868 MHz, <10mW.
*Version with humidity sensor.
**If combined with a central unit BT-CTOLRF
Compliant with: EMC 2014/30/EU - RoHS 2011/65/EU.
