The
46543 HeatLink Digital Thermostat
is a 24Vac electronic thermostat
designed to provide accurate temperature control of hydronic  oor 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  oor sensor; the sensor acts as a  oor temperature limiter
(min / max  oor temperatures are adjustable in the Parameter Menu).

Installation
➀
Remove the Screw Cover.
➁
Remove the Center Screw to separate the Front Control Panel and
Back Terminal Plate.
➂
Mount the Back Terminal Plate using the supplied screws.
➃
Pull the Wiring through the Wiring Holes.
➄
Loosen the Wiring Terminals screws, connect the wires to each of the
terminals as per the wiring diagram, and tighten the screws.
➅
Finish the install by placing the Front Control Panel on to the Back
Terminal Plate, fasten the Center Screw, and replace the Screw Cover.
Mounting Location
•
Mount the thermostat at 5' (1.5 m) from the  oor
•
Mount on inner walls only, and at least 2' (0.6 m) away from any outer
wall. Avoid entrances.
•
Mount away from any direct heat sources like: air vents, radiators, and
lights.
•
Avoid Moisture, it is damaging to electronics, so avoid installing
in areas that would contain high humidity or condensation (e.g.
bathrooms or greenhouses).
•
Do not cover or enclose, allow for proper air circulation, to get a good
measurement of the current air temperature.
Auto-setback mode
(Requires a timer setback signal)
In auto-setback mode, the 46543 operates automatically between
comfort mode (
blinking) and setback mode (
blinking)
according to the schedule of a timer thermostat (46643 or 46673).
Freeze Protection mode
In Freeze Protection mode: instead of simply turning the system
off, this thermostat prevents freezing by maintaining a
6°C (43°F)
minimal temperature. This mode is ideal for unoccupied buildings.
Setback mode
In setback mode, the temperature is set lower to conserve energy, the
default is
17°C (63°F)
. This mode is ideal for areas that are unoccupied.
To change the setback temperature (while in setback mode):
PRESS
OR
to change the setpoint to a lower
(-) or higher (+) temperature
PRESS
The Current Setpoint Temperature will blink
indicating that it can be changed
PRESS
to con rm the desired setpoint
The Measured Temperature will
return after 5 seconds
Comfort mode
In comfort setpoint mode, the temperature is set to a comfortable level,
the default is
21°C (70°F)
. This mode is ideal for occupied areas. To
change the comfort setpoint temperature (while in comfort mode):
PRESS
OR
to change the setpoint to a lower
(-) or higher (+) temperature
PRESS
The Current Setpoint Temperature will blink
indicating that it can be changed
PRESS
to con rm the desired setpoint
The Measured Temperature will
return after 5 seconds

User Operation
In all modes, if a  oor sensor is installed,
blinking indicates that the  oor temperature is outside the limits set by the
FL
