NOTE: Keep the thermostat's air vents clean and free from obstruc­tions.

3.2 Minimum and Maximum Limits

Use the two potentiometers on the
back of the control module to set
the minimum and maximum tem­perature limits. Depending on your

application, the potentiometers
limit the following temperature:

Operation

4.1 Temperature Adjustment

Use the dial on the front of the thermostat to set the desired tempera­ture.

NOTE: If the dial is placed at a temperature beyond the high or low
temperature limit, the temperature will be maintained at that limit (see
section 3.2).

4.2 On/Off Switch

Use the On/Off switch to turn the thermostat Off when it is not used
(e.g., in the summer).

PB130

BN

The PB130-230 power base is used to power an A16c control module.
The resistive load must not exceed 3450 watts (NI) @

Parts

One (1) PB130-230 power base

One (1) oor sensor (for AF and F control modules only)
One (1) wall plate (optional, in certain countries)

Guidelines

Turn o power to the heating system at the main power panel to avoid
electrical shock. Installation should be carried out by an electrician.

All work must conform to the applicable country standards for
electrical installations and wiring.

This thermostat should be connected on a circuit equipped with
a fuse or a circuit breaker. It must be installed on a ce ed
electrical box.

For a new installation, choose a location about 1.5 m above the

oor.

For electric baseboards, convectors and fan-forced heaters, the
thermostat must be installed facing the heating system.

The thermostat must be installed on an inside wall.
Avoid locations where there are air drafts (top of staircase, air

outlet), dead air spots (behind a door), direct sunlight or
concealed chimneys or stove pipes.

• Pilot Wire :
Terminal 3
see note 2

• Floor sensor :
Terminals 6 & 7

see note 3

Note 1 If a contactor is used between the thermostat and the load,

install a snubber at the contactor’s coil terminal to ensure
the proper operation of the thermostat.

Note 2 This connection is required on some models only.

Note 3 For the proper operation of t he thermostat, the

must be centered between two heater wires having a
maximum temperature of 80°C. The
not cross any heater wire or be placed close to it.

Push wires into the electrical box and
secure the base to the electrical box

anchorage. The head of the screw
must be less than 2 mm thick.

BEFORE installing the control
module onto the base, set the

guration switches (if any)

con
on the control module (refer to
