What does Universal Thermostat mean?

The Digistat is universal because it can be used as a fully-programmable thermostat or as a simple manual thermostat. In fact it contains 4 types of functionality:

7-day programmingThe most flexible option allowing you to schedule every day of the week independently.
5-day / 2-day programmingThis groups weekdays and the weekend separately, so you can set a schedule for your weekdays and a separate schedule for the weekend.
24-hour programmingThis gives you the same schedule across every day of the week.
Manual thermostatThis option has no schedule and controls by temperature only. You set your preferred temperature and adjust it with the + and - buttons.
Why should I use the Digistat with the Wiser Heat app?

The Wiser Heat app makes scheduling and adjustments easier, quicker and simpler. The app is completely intuitive and allows you to copy schedules from one day to the next. All from the smartphone in the palm of your hand.

Do I need Wi-Fi or broadband to connect to my Digistat?

No, your smartphone connects directly to the Digistat using Bluetooth (4.2 or later) technology, providing a quick and simple connection when in range (typically at home).

What fuel types does Digistat support?

Digistat supports the following fuel types:

22900BGas, oil, heat pump
2290MGas, oil, heat pump, electric

Depending on the fuel type you select during installation will affect how Digistat works with your boiler/heat source - so ensure to select the correct type during installation.

Does Digistat work with combi-boilers and conventional boilers?

How do you boost?

The Digistat now has a BOOST function. You access this via the O button, selecting the time for the BOOST (30 mins, 1 hour, 2 hours or 3 hours) and the temperature required. When the BOOST has elapsed the Digistat returns to its normal schedule.

The Digistat remembers the last BOOST so if you always use the same parameters just press the O button 3 times. Simple!

What preset schedules are included?

The Digistat includes 3 preset schedules to get you started:

Preset 1 provides heating in the morning and in the evening

The + and – buttons are recessed

When pressing the + and – buttons and tone sounds above and below the set point when audible feedback is enabled.

Can I lock Digistat to prevent tampering?

Yes, go into the Advanced User settings and select option 6 (lock). You will be asked to enter a 3-digit code which will need to be entered later to unlock the Digistat.

What is a real-time clock?
