PLEASE READ THROUGH THESE INSTRUCTIONS BEFORE
PROCEEDING WITH INSTALLATION OF THE “SBFT2”
THERMOSTAT INTO A CADET SERIES “F” BASEBOARD

For All Applications

The thermostat needs to be mounted into the same junc­tion box (wiring compartment) as the supplied electrical
power. If the supplied case ground conductor is not in this
junction box it will need to be relocated to the end wired.

The installation of the SMART-BASE thermostat may
require a slight adjustment of the panel across the front of
the heater, to allow the thermostat to fit into the junction
box unobstructed. To do so, remove both junction box cov­ers and unlatch the bottom of the panel from its hangers.
(Use a rubber-coated tool, or hammer handle to remove
the panel. Carefully pry upward to remove.) Next, slide it
back out of the junction box opening to be used for the
thermostat until its edge is just hanging over the partition.
Hold the panel and snap it back on to its hangers. The
thermostat will now have enough room to fit into the junc­tion box opening.

Replacing Existing BTF Thermostat Control

SBFT2

SMART-BASE Thermostat
Installation Instructions

1. Remove screw attaching the existing BTF assembly
(thermostat and plate) to the baseboard case and care­fully pull it back to expose the wiring and connections.
(Test with meter or circuit tester to verify that no electri­cal power is present before proceeding.)

2. If the power supply has been brought into the base­board at this junction box, undo the wiring connections
and remove the old thermostat assembly. Follow the
appropriate wiring diagram (“FIGURE A” for left end

attachment, “FIGURE B” for right end attachment) and
the following instructions “Baseboard/Thermostat
Wiring” below to connect the SBFT2 to the baseboard
and power supply.

3. If the power supply has not been brought into the base­board at this junction box, remove the old thermostat
assembly by removing the wiring connections. The new
thermostat (SBFT2) must be located in the same junction
box as the supplied electrical power; therefore, strip 1/2"
of insulation from the two loose leads (created when the
thermostat was removed) and join the two wires back
together using a wire connector. Remove the end plate
from the other junction box and apply it to the junction
box where the thermostat was removed. Follow the
appropriate wiring diagram (“FIGURE A” for left end
attachment, “FIGURE B” for right end attachment) and
the following further instructions “Baseboard/Thermostat
Wiring” to connect the SBFT2 to the baseboard and
power supply.

As Part of New Installation

Install the Cadet “F” series baseboard heater according to
the installation instructions supplied with the product. Keep
in mind the SBFT2 thermostat needs to be mounted into the
same junction box (wiring compartment) as the supplied
electrical power. If the supplied case ground conductor is
not in this junction box it will need to be relocated to the
end wired.

IMPORTANT!

It is extremely impor-

tant that you verify
the electrical power
to be supplied to the

heater is the same

voltage as the heater.

Connecting a heater

to a lesser voltage

supply than is intend-

ed will reduce the

heater's output, and

connecting it to a

greater voltage sup-

ply than it is intended

can cause property

damage and personal

injury. The electron-

ic thermostat will
only function cor-

rectly on 240 & 208

volt circuits.

WARNING

Turn the electrical power off at the electrical panel
board (circuit breaker or fuse box) and lock or tag the
panel board door to prevent someone from turning on
power while you are working on the heater. Failure to
do so could result in serious electrical shock, burns,
or possible death.

Baseboard/Thermostat Wiring

Thermostat in left junction box: (Figure A)

1. Locate and cut closed end splice of wires containing limit lead wire
and return wire (wire behind deflector). Strip 1/2" of insulation from
these two cut lead wires.

a. Join the lead wire from the limit with the lead wire from

thermostat terminal J5L2 with a connector.

b. Join the return wire (wire behind deflector) with the lead

wire from thermostat terminal J1T1 with a connector.

2. Connect the grounding lead of the power supply to the supplied
grounding pigtail (copper wire attached to case in junction box) with a
connector.

3. Connect each of the remaining two power supply leads to each lead
from the thermostat rocker switch with a wire connector.

a. Be sure the panel does not interfere with the mounting of

the thermostat plate. Move panel if needed. (Using a rubber­coated tool, or hammer handle; carefully pry upwards.)

4. Carefully push wiring back into junction box, hook upper edge of face­plate under lip of case. Lower bottom edge of faceplate to junction
box surface and secure thermostat with mounting screw.

5. Rocker switch should be placed in the “0” (OFF) position. To finish see
the “Completion of Installation” section below.

Thermostat in right junction box: (Figure B)

1. Cut closed end splice from connection of element lead wire and
return wire (wire behind deflector). Strip 1/2" of insulation from these
two cut lead wires.

a. Join the lead wire from the element with the lead wire

from thermostat terminal J5L2 with a connector.

b. Join the return wire (wire behind deflector) with the lead

wire from thermostat terminal J1T1 with a connector.

2. Connect the grounding lead of the power supply to the supplied
grounding pigtail (copper wire attached to case in junction box) with
a connector.

3. Connect each of the remaining two power supply leads to each lead
from the thermostat rocker switch with a wire connector.

a. Be sure the panel does not interfere with the mounting of

the thermostat plate. Move panel if needed. (Using a rub­ber-coated tool, or hammer handle; carefully pry
upwards.)

4. Carefully push wiring back into junction box, hook upper edge of
faceplate under lip of case. Lower bottom edge of faceplate to junc­tion box surface and secure thermostat with mounting screw.

5. Rocker switch should be placed in the “0” (OFF) position. To finish see
the “Completion of Installation” section below.

FIGURE “A” (Left Junction Box Wiring)

FIGURE “B” (Right Junction Box Wiring)

Completion of Installation

At this point, the baseboard should be securely mounted, and the SBFT2
thermostat wired and secured to the baseboard junction box. The other
junction box should have the baseboard end plate/cover secured in place.

Verify that the thermostat rocker switch is in the “O” (OFF) position before
reestablishing the electrical power at the panel for power flow to the base­board heater.

Refer to the programming guide for the operation of the SBFT2 thermostat.
