Safety Information
Step 1 – Installation
The STRATA_HEAT™Smart LCD Thermostat must be installed by a qualified electrician. It requires a permanent
110V – 240V AC, 60Hz supply. The STRATA_HEAT Smart LCD Thermostat contains a Class A GFCI with 5mA trip
level and wiring must conform to local electrical code.
q
Isolate the STRATA_HEAT Smart LCD Thermostat from the mains supply throughout the installation process.
q
Conduits are only required where it is mandated by state or provincial code. Please refer to local electrical code
for compliant applications.
q
The STRATA_HEAT Smart LCD 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.
q
The STRATA_HEAT Smart LCD Thermostat is suitable for indoor use only. It must not be exposed to moisture,
vibrations, mechanical loads or temperatures outside of its rated values.
q
For safety and licensing reasons unauthorised change and/or modification of the STRATA_HEAT Smart LCD
Thermostat is not permitted.
q
Ensure the distance from your router to the STRATA_HEAT Smart LCD Thermostat is not excessive. This will
ensure the wireless connection is not subject to range or interference issues once installed.
q
Install the STRATA_HEAT Smart LCD 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).
q
Isolate the STRATA_HEAT Smart LCD Thermostat and
supply from the mains supply.
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.
Unclip the display from the power base and remove

Open the MySTRATA_HEAT
App on your phone and
scan this code to proceed
Dismiss
The MySTRATA_HEAT App will guide you through the setup of your STRATA_HEAT Smart LCD Thermostat. You will have to set
up your house location and then the room within which your new STRATA_HEAT Smart LCD Thermostat is located.
Location
A location needs to be setup before a room can be configured and the STRATA_HEAT Smart LCD
Thermostat device registered. Creating a location is user friendly and easy to follow, it is advised to have
details of your current energy tariff and pricing to hand, as these will be required if you wish to use the
energy monitoring features.
Room Setup
With a location now setup, the next step is to register a room in which your STRATA_HEAT Smart LCD
Thermostat is located. This is the heating zone your thermostat will control. Ensure you set the correct
System Type and Wattage of heaters connected.
NOTE: If an external relay or contactor relay has been installed please set System Type as Electric + Relay.
