The HeatmiserNeo Driver 3
Fig. 1 North to Heatmiser Neo
Compatibility with the Heatmiser Neo System
The HeatmiserNeo driver allows North to interface with the Heatmiser Neo underfloor heating and hot
water control system.
The driver connects, via an Ethernet network, to a single Heatmiser neoHub (Fig. 1). The neoHub
supports up to 32 zone devices, including thermostats, time clocks and accessories.
The neoHub zones are polled by the driver for their values. These values are stored and made available as
objects.
Equipment
Heatmiser devices compatible with the driver include:
•neoHub gateway (1st or 2nd generation)
•neoStat thermostats and timeclocks
•neoAir battery-powered thermostats
•neoPlug power sockets
Values
Depending on the type of thermostat or timeclock devices connected, each zone typically has the
following values available:
•Room temperature
•Floor temperature
•Standby mode
•Temperature setpoints
•Comfort level profiles
•Time clock times
•PIN lock
•Hold
•Away
•Output delay
•Program mode
•Temperature format
•Date & time
The HeatmiserNeo system does not generate alarm event messages.

Prerequisites
A neoHub with firmware version 2081 or later is required.
Use the Heatmiser Neo app on a mobile device to set up the neoHub and zones.
The neoHub is assigned an IP address from the local network’s DHCP server; a static IP address cannot be
assigned. If possible, we recommend creating a reservation for the neoHub within the router/DHCP
server. If you are unable to find the IP address of the neoHub from the DHCP server, use the Find neoHub
feature in the driver to scan the IP network.
Be cautious of adjusting values too frequently. The Heatmiser system uses a Zigbee wireless network
with limited bandwidth, sending too many adjustments may cause requests to build up in the neoHub
and the system to slow. Use the Write Messages Sent (A.WC) object to monitor how frequently
adjustments are made.
The neoHub may become slow to respond – typically if there are problems with its wireless network, or
values are adjusted too frequently. Use the neoHub Responding Slowly (A.NS) and Message Reply Time
(A.RT) objects to monitor for this issue. If the driver fails to get a response from the neoHub in a timely
manner, then it will disconnect and stop making requests for two minutes, allowing the Heatmiser
system time to recover.
If you are connecting to a neoHub via a firewall, then the driver will require access to TCP port 4242 on
the Heatmiser neoHub.

The HeatmiserNeo Driver 5
Using the Driver
On ObSys, the HeatmiserNeo driver is pre-installed. On Commander, the driver is available to download
in the file ‘Bank11 HeatmiserNeo.cdm’. On all of these North devices, you can use the driver to create an
interface to Heatmiser. Once started, you will need to set up the driver before it can communicate with
the Heatmiser Neo system.
Starting the Interface
To start an interface using the HeatmiserNeo driver, follow these steps:
Start Engineering your North device using ObSys
Navigate to Configuration, Interfaces, and set a unused Interface to ‘HeatmiserNeo’ to start the
particular interface
Navigate to the top-level of your North device, then rescan it
The driver setup object (Mc), labelled Heatmiser Setup, should now be available. If this object is not
available, check an interface licence is available and the driver is installed.
Setting up the Driver
To set up the driver, follow these steps:
Navigate to the Heatmiser Setup object (Mc). For example, if you started interface 1 with the driver
earlier, then the object reference will be ‘M1’
Set the Host name/IP address object (IA) to the IP address or host name of the neoHub.
Checking Communications
You can check that the interface is communicating by reading the Device Communicating object (DS). A
value of ‘yes’ indicates the driver has connected to, and is communicating with, the neoHub.

The HeatmiserNeo Driver 6
Object Specifications
Once an interface is started, one or more extra objects become available within the top-level object of
the device. As with all North objects, each of these extra objects may contain sub-objects, (and each of
these may contain sub-objects, and so on) - the whole object structure being a multi-layer hierarchy. It is
possible to navigate around the objects using the ObSys Engineering Software.
Each object is specified below, along with its sub-objects.
Example Object Reference
An example of a reference to an object in the same device: the Heatmiser System (S1) contains
Heatmiser zone one (Z1). This zone contains a Standby state(V46). Therefore, the complete object
reference is ‘S1.Z1.V46’.
An example of a reference to an object in a different device: the IP network object (IP) contains Default
Commander object (CDIP), which contains the object above (S1.Z1.V46) – therefore the complete object
reference is ‘IP.CDIP.S1.Z1.V46’.
Device Top-Level Objects
When an interface is started using the HeatmiserNeo driver, the objects below become available within
the top-level object of the device. For example, if interface 1 is started, then the object references ‘M1’
and ‘S1’ become available.

Find neoHub
Object Type: [OSM v20\HeatmiserNeo v20\Find]
Object Type: [CDM v20\HeatmiserNeo v20\Find]
The Find neoHub object triggers the driver to start searching the local network for a neoHub.
A DHCP servers assigns an IP address to the neoHub, and if a local DNS server is available, the neoHub
can be accessed using the host name ‘Neo-hub.yourdomain.com’. If a local DNS server is not available,
and the DHCP server’s IP address leases are not visible, then the Find Now object (N) can find the neoHub
on the network.
Once you have set Find Now object (N) to ‘yes’, the driver will listen for a connect button press on the
neoHub. In addition, the driver attempts each IP address on the local subnet in turn, which can take a
while.
Optional start and end IP addresses may be specified to limit the range of the search. If they are not
specified, then IP address range of the North device is used.
Enable the Auto Find object (A) to re-find the neoHub if its IP address changes.
The State object (S) provides a description of which IP address the driver is currently attempting.

Thermostat
Object Type: [HeatmiserNeo v20\Thermostat]
Object Type: [HeatmiserNeo v10\Thermostat]
A thermostat object contains values for a programmable room thermostat. Typically a neoStat in
thermostat mode.
The neoStat’s Heating Setpoint (V9) object holds the setpoint currently in use for the selected mode. For
example, if the mode changes to ‘standby’, then the frost protect setpoint is copied into the setpoint.
This setpoint can be temporarily overridden if required.
To integrate with another HVAC system, you may need the setpoint when the neoStat is in heating mode,
and not standby. The driver adds this function with the Integration Setpoint (SP) object – providing
either the heating setpoint, or the last setpoint value before the mode changed to standby, hold, away, or
holiday.
For neoStat HC devices, an Integration Cooling Setpoint (CP) is also available – providing either the
cooling setpoint, or the last setpoint value before the mode changed to standby, hold, away, or holiday.
