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.

Please note that using the app will lock out the buttons on the Digistat while the app is open. A lock symbol will appear top left. To go back to using the buttons on the Digistat please close all open apps.

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). A broadband router is not needed. However your smartphone will need a mobile data connection to open and use the app.

What fuel types does Digistat support?

Digistat supports the following fuel types:

22900BGas, oil, heat pump
2290MGas, oil, heat pump, electric
RF901Gas, oil, heat pump
RF902Gas, oil, heat pump

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?

Yes, there is a Digistat to suit both types of boiler – try our product selector to find the right one for you.

Do I need an OpenTherm boiler to use Digistat?

No, Digistat works very efficiently with most boilers and is easy to install. The beauty of Digistat is if you do decide to upgrade to an OpenTherm boiler, our smart control will also be compatible. Note the 2290M and RF901 are OpenTherm compatible.

How do I check that my boiler is OpenTherm enabled?

If your Combi boiler is OpenTherm enabled you should see the an OpenTherm sticker logo on the boiler, as well as in your boiler specific instruction guides. If you are still unsure, contact your installer or manufacturer of the boiler to request clarification.

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 once. Simple!

When a boost is selected, a timer symbol appears in the bottom right of the display and remains until the next event.

Note that a boost can also be used as a temporary setback while you are out. Just select 15°C for up to 3 hours to avoid heating your home while you are out. If this is your last boost, just one press on the O button will setback the heating for the time chosen previously.

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

Preset 2 provides heating in the morning, at noon and in the evening

Preset 3 provides heating all day long

How is Digistat suitable for visually-impaired tenants/homeowners?

The thermostat can be set to manual mode (temperature only)

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.

How is Digistat Boiler Plus compatible?

The Digistat qualifies as one of the additional measures required when replacing a boiler. In fact it qualifies both as a Smart Control and as Load Compensation.

Which Digistats are being replaced?
2290BReplaces 22192, 22084, 22083, 22102 and 22104
2290MReplaces 22103, 22088, 22087, 22103 and 22105
RF901Replaces RF710, RF700, RF701, RF703 and RF704
RF902Replaces 22190, 22090, 22092, 22111 and 22110
What is a real-time clock?

A real-time clock means that you don’t need to set the time or date when you first use your Digistat – it is factory set during manufacture. In addition you don’t need to worry about summer/winter time changes as this is also done automatically by the Digistat.

Pairing with your Digistat – can’t see the pop-up?

There are a number of reasons why the Bluetooth pop-up does not appear instantly:

  1. There may be other Digistats powered up and within range and this will slow down the pairing process. If it is possible to depower the other Digistat please do this while you are pairing, or if not then press “I have done these steps” and wait for the RETRY button to appear. On the second attempt the pop-up should appear instantly.
  2. There are known issues using Bluetooth with some later Apple devices. However the RETRY button should allow you to pair your Digistat within a few attempts.
  1. There are also known issues when pairing with Samsung smartphones using Android 11. Please change to an earlier or later version of Android.
What does "Optimised Settings" mean?

These settings appear in the installer menu and it is important to select the setting for your heat source: gas boiler (default), oil boiler, heat pump, or electric heating

  • When used with a gas boiler the Digistat will automatically cycle the boiler to help your boiler to run more efficiently and save you 10% on your heating bill (compared to a simple ON/OFF thermostat).
  • When used with a Heat Pump the Digistat will protect the compressor by reducing cycling to 3 cycles per hour, to improve the life of the compressor.
  • When used with an oil boiler the Digistat will allow the boiler to run without cycling for improved efficiency.
  • When used with electric heating the Digistat cycles the heater at 12 cycles per hour to maintain room temperature and save money.
How do RF versions pair with the receiver?

As soon as both the Receiver and Thermostat are powered up they will automatically pair.

However this auto-pairing process only lasts 2 minutes (to avoid issues of pairing with the wrong Digistat). If you find that the 2-minute auto-pairing period has expired, please follow the following process:

  1. Reset the Digistat thermostat by going into the setting menu, selecting the Inst03 menu (installer settings) and then rSEt20 to reset to factory settings. Then remove the batteries.
  2. Reset the Receiver by pressing the button for about 15 seconds until you see a red light followed by flashing orange/green which shows it is in pairing mode.
  3. Put the batteries back in the thermostat and they will now pair automatically.
How do I change from heating to hot water on the Digistat RF902?

To swap between Heating and Hot Water on the thermostat press the setting button (cog symbol) to open this open.

Flashing radiator icon on the display = heating.

Use the + or – buttons to change to hot water (flashing tap icon) and select with the O button.

In either mode the radiator or tap icon will be displayed.

How do I change from Automatic to Manual mode?

Press and hold the settings (cog symbol) button for 3 seconds to access the setting menu. Then select USEr01 by pressing the O button. Select MOdE and then use the up or down arrows to select AUTO or MAN. Confirm by pressing O. Use the back button (cog symbol) to exit.
