This device complies with Part 15 of the FCC rules: Operation is subject to the following conditions: (1) this device may
not cause interference, and (2) this device must accept any interference, including interference that may cause undesired
operation of this device

Antenna Connection - The Wirsbo Genius™ control system is designed to use a radio

signal opposed to typical low voltage wiring. The external antenna provided must be
connected for proper system operation.

Cooling Contact - When the Wirsbo Genius is operating in “cooling” mode, this
connection can be used enable an air handle, furnace, etc., for air conditioning
requirements. This contact is locked out in the heating and off modes. This is an
unpowered or dry contact.

Heating Contact - When the Wirsbo Genius is operating in “heating” mode, this
connection can be used to enable a boiler, pump relay or other types of heating devices.
This is an unpowered or dry contact.

Mode Indicator LED - The LED changes color to indicate the mode of operation. The
indicator will change from Orange (off) to Red (Heating) to Green (Cooling). These
LEDs are visible through a display window on the front cover on the Genius™

Mode Selector Switch - Used to change mode of operation (Off-Heat-Cool) on the
Genius™ When the front cover is installed, this switch can be operated by pressing the
right hand corner of the display window.

Modular Connector - This port is used during the installation of the Radio Thermostats.
Using the cable provided with this package, one end is plugged into this port and the other
into the back of the Radio Thermostats. See Section XX for Radio Thermostat
Initialization.

Modular Zone Output - These 10 connections are for operation and connection of the
DC-style Motorized Valve Actuator (MVA). The female connector on the Genius board
is keyed to ensure the plug on the DC-MVA is wired properly.
Important: The Wirsbo Genius is designed for use with the DC-MVA only. Use of other
unapproved actuators will provide unsatisfactory operation.

Power Supply - The Wirsbo Genius Base Unit comes pre-wired with a 6’ power cord and
plug. Simply plug in to standard 115 volt receptacles.

Pump Connection - Power supply to a circulator (if used) in a radiant or other hydronic
application. This output is only active in the heating mode.

Status Indicator LEDs - Visible through the display window when the cover is installed,
these LEDs will change color and flash to provide systems feedback (communication,

error, valve failure, antenna signal strength, etc.). Through out this manual, these LEDs
will be discussed in further detail based on the mode of operation.

Temperature Units Switch - This switch position will determine whether the Radio
Thermostat will display temperature in °F or °C. Units must be selected prior to installing
the Thermostats.

User Interface Buttons - These are used during system initialization and are not required
for normal operation. See pages xx-xx for additional information.

Section 2: System Overview:

The Wirsbo Genius system is a radio controlled system for radiant floor heating and other
hydronic applications. Primary system components are Radio Thermostat, the Base Unit
and the DC-style Motorized Valve Actuator (MVA) as shown below.

Fig 1. Fig.2 Fig.3

The Radio Thermostat (see Fig. 1) communicates with the Base Unit using a completely
wireless link, highlighting ultimate flexibility of placement for indoor temperature
feedback. The Radio Thermostat are mounted on a wall of an area designated as a
“zone”. A zone can be a single room, multiple rooms, a garage or any area where space
temperature control is desired or required. The radio signal and frequency used to
transmit information between the two pieces of hardware will not interfere with common
household appliances such as the microwaves, garage door openers, televisions, etc. The
Radio Thermostat transmits identification number, change in space temperature (actual vs.
setpoint) and will also “talk” to the Base Unit on a random interval to ensure
communication is uninterrupted. Upon a recognized change in room temperature sensed
by the Radio Thermostat, the Base Unit will perform secondary operations based on the
mode of operation (heating or cooling).

The Base Unit (see Fig. 2) upon receiving a change in temperature from the Radio
Thermostat will provide the necessary switching for control outputs based on the mode of
operation. The Wirsbo Genius™ will control:

Heating Mode

• Up to 10 DC-MVA, part number A302xxxx

• One 110 VAC circulation pump or other powered output; max rating ½ HP /

400 VA

• One optional dry contact for interfacing boiler operation or other heating

controls; max rating 110 V, ½ HP / 400VA

Cooling Mode

• One optional dry contact for interfacing air conditioning; max rating 110 V,

½ HP / 400VA

The Base Unit is mounted at the manifold location(s) and can receive communication from
up to 10 Radio Thermostat. Through the Base Unit, each Radio Thermostat has the
ability to control 1 or more outputs to the DC-MVAs by “Zone Mapping”. Simply, Zone
Mapping is the relationship between the Radio Thermostat controlling the proper zone
outputs or DC-MVAs, reacting to a fall in room temperature. Zone Mapping is

established during the installation of the Wirsbo Genius™ system and will be covered in
greater detail in Section XX.

The DC-MVAs (see Fig. 3) will open and close, dependent on the signal that Base Unit
receives from the Radio Thermostat, allowing water to circulate through the
corresponding loops of the manifold. The DC-MVA is unique in its design as it does not
require power to remain in the open position; power open/power close. The DC-MVA
has an integral end switch that serves multiple functions. It will not allow the pump to
start until a minimum of 1 end switch has closed during a call for heat and also provides
system feedback through the User Interface to indicate a operator or DC-MVA failure.

Section 3: User Interface

Prior to progressing to the installation of the Wirsbo Genius, it is important to understand
the User Interface and how it works. There are two parts: the buttons (User Interface
Butttons and the Mode Selector Switch) and the LEDs (Status Indicator LEDs and the
Mode Indicator LED). The buttons are used to provide a minimal amount of information
in order to make the Wirsbo Genius operational. The LEDs change color to indicate
certain system functions depending on the mode (installation or normal operation) and are
visible through a clear window after the cover is installed. Once the Wirsbo Genius is
programmed and the cover secured, only the Mode Selector Switch will be required to
change the mode of operation from Off to Heat to Cool. See Fig. 4.

Section 4: Getting Started

To begin system start up and programming of the Wirsbo Genius, we highly recommend
that the programming be completed prior to mounting the Base Unit at the manifold
location. The installation of the Radio Thermostats to the Base Unit can be completed
much easier on a flat surface, such as a desk or table top.

1.) Remove the Base Unit and the required number of Radio Thermostats from their

packaging.

2.) Verify that all the necessary components are included in the packaging. As follows:
