The 46543 HeatLink Digital Thermostat is a 24Vac electronic thermostat
designed to provide accurate temperature control of hydronic floor heating
systems. Features include:
• Large 2" (50 mm) LCD display, with a large temperature display.
• Proportional plus Integral (PI) controlled temperature regulation.
Proportional moves quickly to the desired setpoint and slows down when
the desired setpoint is near. Integral compensates the proportional offset
(overshoot) and stays close to the setpoint.
• Fast switching between modes; temperature setpoint is adjustable at the
press of a button.
• Accepts timer signal for automated setback operation (requires 46643
Timer Thermostat or 46673 Heat/Cool Thermostat).
• Floor warming functionality is available through NTC terminal by adding
an optional 10K floor sensor; the sensor acts as a floor temperature limiter
(min / max floor temperatures are adjustable in the Parameter Menu).
