Install the STRATA_HEAT Wi-Fi Thermostat in an area with good ventilation. It should not be beside a window/
door, in direct sunlight or above another heat generating device (e.g. radiator or TV).
Ensure the distance from your router to the STRATA_HEAT Wi-Fi Thermostat is not excessive. This will ensure the
wireless connection is not subject to range or interference issues once installed.
Conduits are only required where it is mandated by state or provincial code. Please refer to local electrical code
for compliant applications.
The STRATA_HEAT Wi-Fi Thermostat and its packaging are not toys; do not allow children to play with them.
Small components and packaging present a risk of choking or suffocation.
The STRATA_HEAT Wi-Fi Thermostat is suitable for indoor use only. It must not be exposed to moisture,
vibrations, mechanical loads or temperatures outside of its rated values.
For safety and licensing reasons, unauthorised change and/or modification of the STRATA_HEAT Wi-Fi Thermostat
is not permitted.
Install a 3-1/2"(89 mm) deep single gang or 2-gang box with mud ring in your preferred thermostat location.
Pull wires (heater, supply and sensor) through gang box and complete terminal wiring.
