thermio™ 103

PRODUCT DESCRIPTION

The thermio™ 103 are room thermostats with thermal feedback. The comfort temperature can be conveniently controlled and monitored by a large rotary knob with a wide control range. The high control accuracy and low power consumption contribute to the reduction of energy costs. These two variants are distinguished by their slim design and easy mounting on flush-mounted boxes.
