Description
The SOLO thermostat is designed to control the temperature of a
floor heating system for both 120-volt and 240-volt applications. The
thermostat can be used to control either the floor temperature or the
ambient temperature. It has a maximum load capacity of 15 A (1800
W @ 120 VAC or 3600 W @ 240 VAC).
SUPPLIED PARTS
•
One (1) thermostat
•
One (1) floor temperature sensor
•
Four (4) solderless connectors
•
Two (2) 6-32 mounting screws
•
One (1) flat-tip screwdriver
OPTIONAL ACCESSORY (SOLD SEPARATELY)
•
Honeywell outdoor sensor AC629 (for outdoor temperature and
humidity readings). Refer to section 10.

Installation

TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER
PANEL TO AVOID ELECTRICAL SHOCK. THE INSTALLATION MUST
BE PERFORMED BY A QUALIFIED ELECTRICIAN.
The thermostat's housing is not watertight. Do NOT install the

NOTE: All wires and connections must conform to the local electrical
code. This thermostat has tinned copper wires for line and load
connections. Special CO/ALR solderless connectors must be used if
these wires are to be connected to aluminium conductors.

Programmable Dual Voltage Thermostat
Connect the thermostat wires to the power supply and to the load
using solderless connectors for copper wires as shown below.

Pull the temperature sensor wires through one of the openings
on the thermostat base and connect the wires to terminals 1 and
2 (no polarity).
•
The sensor cable must not come in contact with the
electrical wires and must be routed outside the electrical
box and follow the wall down to the floor.
•
Position the sensor cable such that it does not come in
contact with the floor heating wires. The sensor must be
centered between two floor heating wires for best
temperature control.
•
Do NOT staple the sensor head (the plastic end) to the floor.
Doing so might damage the sensor. The damage might not
be noticeable during testing but can become apparent
several days later.
Network and outdoor sensor connections
(refer to sections 9 & 10)
Push the excess length of the line voltage wires back inside the
electrical box. Install the thermostat base onto the electrical box
using the provided screws.
Set the DIP switches (refer to section 2.1).
