INTRODUCTION
The STRATA_HEAT™Programmable Thermostat default screen is the home screen. Pressing the temperature figure in the center of the
screen allows you to override it. Pressing the menu button allows you to start programming and setting up the STRATA_HEAT Programmable
Thermostat. You’ll often find a help button on pages with several options to give more information.
If you do not press any button for 1 minute, the STRATA_HEAT Programmable Thermostat screen will dim and revert to the home screen. To
wake the STRATA_HEAT Programmable Thermostat just tap the screen or press Wake.
To turn the thermostat on or off, press the power button on the bottom of the device for 3 seconds.

SET YOUR HEATING PROGRAM
With your STRATA_HEAT™Programmable Thermostat, you can choose to set a custom heating schedule, fixed temperature or a preset
program designed for different rooms.
To adjust the program, you must highlight the days that you want to program by pressing them, then press Program. You can select multiple days in
any combination, such as weekdays only, to program separate weekday and weekend temperatures. To do this, program all the weekdays at once and
then program the weekend when you’re finished.
The programming works by setting Comfort Periods of warm temperatures, shown with a green line. Any time not covered by a Comfort Period will
use a lower Setback temperature to save energy. The default setback temperature is 60°F (15°C)and you can change this once you’ve set up your
program if needed.
You can add up to 5 Comfort Periods per day and when you’ve set what you want, just press Done. You’ll see the summary of your program which
you can edit by repeating the steps above, or just press Accept to set your program.
Remember: The STRATA_HEAT Programmable Thermostat can also learn your schedule and program itself. To activate
this, set it into Learning Mode.

HOLIDAY MODE
Holiday Mode allows you to override your schedule with a fixed temperature over a number of days. This helps you save energy when you know
you’ll be away for a while by setting a lower temperature. Holiday Mode can be found in the Program menu
Just set the start and end times of your holiday, or leave the end time as Unspecified, if you want Holiday Mode to run indefinitely. Then set the
temperature you want when you’re away.
GRADUAL START
Gradual Start allows you to bring your floor up to temperature slowly, which is required for some floor finishes such as solid wood, and can also be
found in the Program menu.
Enter the maximum temperature and the time required to reach that temperature to set Gradual Start. Different floors have different requirements
so please contact your floor installer or supplier for advice on how to set Gradual Start correctly.
FROST PROTECT
Select Frost Protect mode to set your heating to 40°F (4°C). This will help protect your home from frost and will run continuously until you raise
the temperature again.

ENERGY MONITOR
The STRATA_HEAT™Programmable Thermostat learns how you use your system and how your house reacts to the heating and weather. It
can give you an estimate of your energy usage and the running cost of your system.
You will need to enter the power of your system, and in some cases, the efficiency. If you do not know these, speak to your installer or go to
mystrataheat.com and use our online Heat Requirement Calculator.
You will also need to enter the cost of your energy, in order to calculate the running cost of your system. Press Energy Settings, and select if you
have a single rate or a standard/low energy rate (where you have a discounted cost during part of the day). Enter your cost per KWH and relevant
currency and, if required, the time the low energy rate starts and stops and the discounted cost during that time.
When you’ve set up the Energy Monitor you can view the estimated usage or cost over a selected time period. If you have a standard/low energy
rate, the amount and cost of energy used during the standard period will be displayed in dark green and the amount used in the low period will be
displayed in light green.

Introduction
The STRATA_HEAT™ Programmable Thermostat is designed to aid in the comfort of your home by providing timed regulation of your heating system. The thermostat
is designed to receive temperature input signals from the following sensors:
1. Air sensor located inside thermostat
2. Floor sensor installed in floor if using underfloor heating (See STRATA_HEAT Wire Installation Manual for details.)
3. Optional 2nd sensor
The thermostat is not a safety device. In order to avoid damaging your system the correct system and floor type should be selected during the thermostat programming process.
Electrical Specification:
nSupply voltage: 110V-240V +/-15% at 60Hz
nThermostat is not designed for use with intermittent power supply.
nMaximum Switch Load: 15A resistive
nInsulation Class: II
nHousing: Electrical Code Requirements
nStandards: EN60730-1 & EN60730-2-9 standards
WARNING – Important safety note
This product uses mains voltage electricity and work should only be carried out by a qualified electrician. You should always isolate the power supply before attempting to
install or repair the STRATA_HEAT™ Programmable Thermostat. The thermostat should not be put into operation unless you are certain that the entire heating installation
complies with current general safety requirements for electrical installations. Electrical installation to be in accordance with latest Electrical Code Requirements.
Location
The thermostat should be installed inside a single gang electrical wall box that is at least 1 1/4" (32 mm) deep. For optimal performance the thermostat should be located
in an area with good ventilation. It should not be beside a drafty window/door, in direct sunlight or above another heat generating device (e.g. radiator or TV).
The thermostat is designed for operation between 32 - 131°F (0 - 55°C) with relative humidity less than 80%.

Installation
Separate the front housing of thermostat from wall module:
1. Unscrew both closing screws (bottom of stat) until they will not
turn any further.
2. Release front housing by gripping lower half of outer frame and
pulling outwards then upwards
3. Place front housing somewhere safe
4. Run all wires to the wall box. Check to ensure that you have
included the following:
Power (Live and Neutral)
Heater (Live and Neutral or Switch Live only)
Floor sensor
Fil pilote (if necessary)
External/ 2nd floor Sensor (if necessary)
5. Pull wires through wall box and complete terminal wiring.
IMPORTANT: Ensure that multi stranded wires are fully inserted into the
terminals and secured tightly. Any loose strands should be trimmed as
they could cause a short-circuit.
If connecting more than two heaters, an electrical junction box will be
required.
NOTE: Always ensure that the sensor cable is installed in a separate
conduit to the power cables supplying the thermostat and heating
system.
