Instructions
For models: OTH700S (240GA) /
OTH702S (120GA) / OTH800D (240D)
Material
! One (1) power base
" Two (2) screws
# Four (4) solderless connectors for copper wires
NOTE: Special CO/ALR solderless connectors must be used when
connecting with aluminum conductors.
$ One (1) floor sensor and one (1) flat tip screwdriver (OTH700
series only)
Installation Guidelines
Turn off power to the heating system at the main power panel
to avoid electrical shock. Installation should be carried out by
an electrician.
High voltage thermostats must be installed onto an electrical
box.
For a new installation, choose a location about 5 ft. above the
floor.
The thermostat must be installed facing the heating system
(except for floor heating installations) and on an inside wall.
Avoid locations where there are air drafts (top of staircase, air
outlet), dead air spots (behind a door), direct sunlight, con-
cealed chimneys or pipes or an air diffuser.

Installation Steps
! Connect the rear power base wires (FIGURE 1) to the power
and to the load using solderless connectors for copper wires.
Connecting the floor sensor (Figure 2)
• Insert the probe into one of the two holes available below
the terminal board and connect the wires to terminals 3 and
4 (no polarity needs to be respected).
• The cable follow the wall down to the floor and must not
cross any heating wires nor be directly on or adjacent to a
heating wire. For maximum performance, the sensor probe
should be centered between the wires in the mat. Run the
sensor in a raceway for easy access to a defective sensor.
Connecting the econo input (Figure 2)
• Insert the cable (use an 18 to 22 gauge flexible wirecable)
into one of the two holes available below the terminal board
and connect terminals 1 and 2 of the base to terminals 1
and 2 of the CT240’s auxiliary output or any of the dry con-
tact outputs of the CT241 (Aube telephone controllers).
" Push the excess wire (except for the probe/econo) back into
the electrical box to prevent interference with the thermostat.
Warning: the cable must run on the left side of the cavity
located on top of the terminal board. Secure the power base
to the electrical box using the provided screws.
# BEFORE mounting the control module onto the base,
configure the switches located on the control module (heating
cycles * and display) and install the control module onto the
base (refer to the control module user guide).
*
this power base must be used only with 15-minute heating cycles.
$ Once the control module is installed onto the power base,
return power to heating system.
