The IMIT 578160 Techno Duo thermostat is easy to use and very straightforward, ideal for precise daily adjustment without any difficulties. It is designed to meet all the requirements of residential temperature control, so it offers 24-hour programming and two temperature levels.

The IMIT 578160 Techno Duo thermostat is easy to install. It connects to the boiler with the thermostat contact, and in its relay function, it either activates or deactivates the heating by closing the thermostat contact.

The display is backlit, allowing you to clearly see all the operating parameters. The levers allow for immediate adjustment of the operating hours.

Adjustments and Display

The adjustments are extremely simple, always rely on:

  • The flame symbol for heating call, this symbol indicates that the thermostat is signaling the boiler to heat.

The Display

The display of this thermostat shows you the essential operating information. There aren't numerous symbols like in other thermostats that might cause confusion.

  • Prominently displayed, you can see the current ambient temperature or the currently set time.
  • You can switch the display between time/temperature by pressing the Set/clock button.
  • 'AUTO' is displayed if the thermostat is in automatic mode (active hours and temperatures).
  • 'MAN' is displayed if the thermostat is in manual mode (only one temperature is used throughout the day).

Button Functions

The buttons are as follows:

  • On the left, you can see the heating programming levers,
    • When they are pointed downwards, it indicates that the heating is set to economy mode during that time.
    • When they are pointed upwards, it indicates that the heating is set to comfort mode during that time.
  • On the right, starting from the top:
    • The + and - buttons are for adjusting the economy temperature (Moon Symbol).
    • The wheel is for adjusting the on temperature (Comfort).
    • The button to adjust the clock (Set / Clock).
    • The Mode button toggles operation between:
      • AUTO = Automatic
      • MAN = Manual
      • OFF = Off.

Set the Correct Time

Instructions to set the correct time on the thermostat's display.

Set an Operation Schedule

To set a functioning program, after setting the time, proceed as follows:

  • On the left, read the levers with their respective times.
  • Position the lever of the time you want to turn on upwards.
  • Alternatively, you can choose to turn off the heating. Decide the off times and position the respective levers downward.

Setting the Operating Temperatures

To set the economy temperature, use the + and - buttons next to the moon symbol in the top left.

  • Choose an off temperature of about 16/17 degrees.

To set the comfort temperature, use the large wheel instead. The set temperature value will flash on the display.

Common Issues

The thermostat isn't turning on the heating!

Assuming that the batteries are charged, disposable, and of excellent quality.

We suggest starting a check from the boiler:

  • Ensure that the boiler pressure is correct (between 1 and 2 bars).
  • Ensure that the boiler is correctly set to winter operation.

Next, you can perform a simple check:

  • Press the MODE button to select the MAN (Manual) mode.
  • Raise the temperature using the large knob to a very high value.
  • The flame symbol should appear on the display, and within a few minutes, your heating should start operating.

At the end of this test, remember to reset the comfort temperature to 18/20 degrees, depending on your preferences, and conclude by checking:

  • That the time is correct for automatic mode.
  • That the program is set to turn on for the current time.

Frequently Asked Questions

Your questions and the most frequently posed ones:

How can I set the time on the IMIT 578160 thermostat?

Press and hold the SET / Clock button; the display will begin to flash the minutes. Then use the + and - buttons at the top right (next to the moon symbol) to adjust the minutes.

Press the SET / Clock button again to move to hour setting. Complete the setting by saving with SET.

What is the average battery life when used continuously?

The batteries should last for about two years; however, we suggest replacing them annually.

Use ONLY non-rechargeable batteries from a reputable brand. Rechargeable batteries have low amperage and might not correctly activate the heating, causing discontinuities.

How do I switch from "AUTO" mode to "MAN" mode?

Press the MODE button. The three states (AUTO / MAN / OFF) change with each press.

What are the differences between NORMAL temperature (T1) and REDUCED temperature (T2)?

Use the normal or Comfort temperature during the hours when the apartment is occupied, such as during the day.

We suggest using the reduced temperature during the nighttime and possibly during the day.

What can I do if the thermostat doesn't turn on the heating?

Check to see if the flame symbol appears on the display; this symbol indicates if the thermostat is correctly calling for heat. Otherwise, ensure that the current set temperature is higher than the detected temperature.

How exactly do the heating programming levers work?

The levers are designed to give you precise control during significant hours, for instance:

  • From Midnight to 5 in the morning, there's only one lever.
  • After 5 am, the levers allow for half-hour adjustments, providing more precise control.

Levers in the high position mean that the heating during those hours will follow the comfort temperature (large wheel).

Levers in the low position will follow the reduced temperature (economy).

Is it possible to use the thermostat for underfloor heating systems?

Yes, it is possible, but it's not recommended as long pauses could result in heat loss from the slab.

In general, the thermostat is designed for more responsive systems such as:

  • Cast iron radiators,
  • Aluminum radiators,
  • Fancoils.

Useful Tips

You can use some helpful tips, for example:

  • For heating systems with cast iron radiators, you should take into account the time needed to heat up the apartment, so start the heating at least 1 hour in advance. However, you can turn off the heating early to take advantage of the thermal inertia of this heating material.
  • For systems with aluminum radiators, given the high operating temperature required for optimal performance, you can use a shorter lead time and turn off the heating at the exact time.
  • The thermostat, however, is not very suitable for underfloor heating.

The Batteries

Remember to replace the batteries of this thermostat approximately every year. However, we are informed that the thermostat can continue to work correctly for about 2 years.

Mounting and Installation

The installation of this thermostat is relatively simple. Operating in relay mode, it is necessary to use the Normally Open and Common contacts of the terminal block.

If installed as a replacement for a previous thermostat, just use the boiler contacts of the former. Otherwise, a connection between the boiler and thermostat must be prepared.

Always consult a professional for the installation of this product.
