Create the perfect comfort zone 

evohome multi-zone system



evohome is a sophisticated heating system that ensures
you can create and individually control up to 12 heating zones in domestic properties. evohome will also control domestic hot water.
evohome is suitable for any home with a hydronic (wet) central heating system. Zoning solutions can be designed for even the simplest of property layouts. evohome is ideal when looking to control temperatures in larger properties such as: luxury apartments; large family homes; homes with business use; multiple occupancy apartments and light commercial spaces such as doctors surgeries and small offices.
evohome allows the installation of multiple temperature sensing devices around the property without altering existing pipework, disrupting décor or damaging fixtures and fittings.
With touchscreen control, the user can quickly gain control of exactly where and when the property should be heated.
Remote access is provided via a tablet or smart phone.
Wireless Radiator Controllers provide an easy way of installing heating zones without draining down or disturbing pipes or décor. evohome really is the brain of the heating system.

evohome controller

evo

The multi-zone evohome controller controls the time and temperature of up to 12 heating zones plus a domestic hot water supply if required. Each zone has independent time and temperature control.

It has a backlit colour LCD screen. The unit can either be wall mounted with an external power supply or table mounted on the table stand. This is powered by a 13amp power cable.
The evohome controller can be removed from the stand for easy programming for up to 2 hours before returning to the stand for charging.

The colour of the surround can be changed to either black or silver. A choice of idle screens, analogue or digital clock displays and a choice of day or night mode increases the aesthetic properties of the most visible part of the evohome system. When controlling the heating system the evohome controller has a number of features that make operation easy.

The evohome controller can act as a room thermostat on its own. Zone names can be input to match the actual property and the zones can be controlled as multi-room or as single-room zones. Zones can be configured to give individual local override of a room or rooms within the zone.

The programming in the unit is split between in-use and installation sections with a wide variety of control choices for the property owner. There is a guided scheduling wizard for the property owner to help them set up time and temperature profiles in each zone and a guided configuration facility for installers.

The screen will show energy efficiency messages to the homeowner as each zone’s temperature will be colour coded to show potential over or under set point temperatures.

  • There are a number of quick actions available to make it easy to change the heating requirements for a short period.
  • „„Day Off mode changes the schedule for all the zones to a pre-set day (i.e. change a week day to a weekend day)

„„The Heating Off button will turn all the zones off unless the frost protection temperature level is reached

The evohome controller provides access for the installer to fully control the heating system.
It is suitable for radiators, hydronic
under floor and a mixture of both types of heating. Cycle rates, minimum on times and fail safe parameters can be set.

OpenTherm® capability is built-in to work with OpenTherm® boilers (not hot water systems). Boilers can be controlled by either a boiler relay or an OpenTherm® bridge. You can programme a temperature offset for the evohome controller screen when used as a temperature sensor in its own right.

Hot water cylinder overrun and temperature offset levels can be programmed as can the hot water temperature itself. You can carry out a wireless Radio Frequency (RF) check using the evohome controller screen. Wireless binding of the system components is carried out via the touchscreen and additional sensors can be easily bound in post application if the zoning requirements change.

In-built optimisation features such as ‘delayed start’ and ‘optimum stop’ allow evohome to intelligently optimise start and stop times. A learning TPI algorithm ensures each zone adapts to the weather and the seasons.

Digital room thermostats

Where there is a requirement to use a wireless room thermostat as a temperature sensor, both Honeywell’s DT92 Digital Room Thermostat and the Y87 Single Zone Room Thermostat can be included into the evohome system.

Easy to set up with two way wireless communication (30m range) and a signal strength indicator. Simple to operate with up and down buttons (DT92) or by a turn of the Dial (Y87). Individual zone temperature override.

5 to 35°C set point range offers a wide range of comfort levels. The DT92 digital thermostat can be wall mounted or free standing to ensure best possible positioning. Y87 Single zone thermostat is wall mounted

Wireless relay

The remote relay is wired into either a motorised zone valve or the boiler and provides the wireless interface between these devices and the evohome system. The relay box requires a permanent 230V~ supply.

Wireless cylinder thermostat

Control domestic hot water via the evohome controller screen by installing an externally- mounted wireless cylinder thermostat onto the hot water cylinder; Sensors are provided for vented and unvented cylinders.

Honeywell’s externally-mounted wireless cylinder thermostat is a combination of a temperature sensor that is mounted against the metal of the hot water cylinder and a wireless battery powered transceiver that communicates the water temperature to the evotouch controller.

Under floor heating controller

By controlling the hydronic under floor heating via the Honeywell under floor heating controller, the time and temperature of the under floor heating can be achieved via the evohome controller screen.

The under floor heating controller provides for up to 5 zones of under floor heating and the optional extension controls a further
3 zones. It operates on the same 868 MHz frequency as the rest of the evohome components and has an internal antenna.

Remote access gateway

To enable the evohome system to be controlled remotely by either a wifi-enabled tablet or smartphone, a remote access gateway needs to be connected to the internet network within the property.

LED lights are provided on the gateway for feedback during binding and operation. This is achieved by connecting the supplied ethernet cable into the remote access gateway and a spare ethernet port on the home broadband router.

The remote access gateway is powered by a supplied 13 amp power supply and there is one button binding of the gateway to the evohome system via the evohome controller.

Once bound, the homeowner is then able to visit the total connect website to register their evohome system, uniquely identify their evohome remote access gateway (MAC ID & CRC code) and receive instructions on how to download the smartphone or tablet app that suits their Apple or Android system.

Smartphone or tablet app

The smartphone or tablet app that enables remote control of the evohome system will be available for download from the iTunes Store and the Google Play store.
