Dimplex DTK Series, DTKT Series Installation Instructions Manual
Thermostat Kits
DTK & DTKT Series (Tamper proof)
General Instructions
For use with Dimplex baseboard heaters series BN, DBH
and LC.
DTK-SP and DTKT-SP thermostat kit is design to work as
freeze guard. It does not have a true “off” setting. When
set to its lowest position, by counter clockwise rotation of
the shaft to last stop, the thermostat cycles the heater on at
approximately 4.4° C (40° F).
DTK-DP and DTKT-DP thermostat kits are design to have
a positive “off”. The thermostat is in “off” position when
the shaft is turned counter clockwise to last stop usually
after a slight “click”. At this setting the heater will not cycle
regardless of room temperature.

Operation
CAUTION:This thermostat must be properly installed
before it is used.
The built-in thermostat senses the temperature of the air at
the baseboard and must be set by trial to provide optimum
room comfort. When rst operating baseboard heater, turn
thermostat knob clockwise to last stop. Within a short period
of time the room will be at desired temperature. Turn the
thermostat knob counter clockwise until baseboard goes off
(you will hear a slight “click” ). Keep thermostat knob at that
setting and temperature will be automatically maintained.
Maintenance
CAUTION: Before removing the front cover for cleaning,
make certain the power has been turned off at the circuit
breaker panel.
CAUTION: Allow adequate time for the element and body
casing to cool before attempting to work on the heater.

NOTE:See Heater Manual for Cleaning Instructions.
WARNING: The user can perform cleaning ONLY, all
other servicing should be performed by qualied service
personnel.
