WATTS langaton termostaatti BT-D02 RF
Description
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="" a="" central="" unit="" bt-ctolrf="" compliant="" with:="" emc="" 2014="" 30="" eu="" -="" rohs="" 2011="" 65="" p="">
