Nuheat TEMPO User Manual

Description

The Tempo 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).

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. Any damages might not
be noticeable during testing but can become apparent
several days later.
To remote control device (see section 7.2)
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 3).
