Language Option
To select the required language press PROG and enter the code 2305 and press Enter. Then select the
required language from the selection.
Standard Terms
Self Learning Optimisation is a system whereby the Heatmiser Control will automatically calculate the
start up time to ensure the building is up to temperature for the programmed switching time. It does this by
monitoring the internal temperature readings, so that for example, in milder weather conditions heat up times
are reduced - thus saving energy.
Preheat is the number of hours the control can come on before the programmed switching time (when in
optimising mode) This is setup under the Engineers code and can be set to no more than 8 hours.
Rate of Change is the time it takes to raise the building by 1.0°C. The factory default for this setting is 20
minutes but the control will automatically adjust this according to the fabric of the building.
Override Using the override button on the Heatmiser keypad allows the user to override the zone for a selected
number of hours, to allow for unscheduled use of the system. A maximum can be set to stop users entering
long override periods.
Switching period status:
• Day is when the control is being controlled to an actual switching time (For example between 07.00
- 17.00 the control would be in a DAY condition) Outside of these hours the control would be in a
night condition.
• Night is when no switching times have been programmed. At these times the control is set back to
the night temperature.
Heater Lockout and Reset is standard on the Heatmiser Mistral and allows for a signal to be fed into the
Heatmiser from the heater when the heater goes to lockout (overheat etc) Once the fault on the heater has
been rectified a reset signal can be sent to the heater resetting lockout status.
Normal RUN Mode is when the control is operating normally and is not being programmed (ie showing
the time and date screen). It is important to remember that when any alterations have been made to the
Heatmiser’s program, the RUN button is pressed to return the control to the RUN mode.
Normal RUN Mode
There is one main Normal (Run) mode screen, and one Info screen on the Heatmiser IQ+. These are explained
below;
On/Off RUN mode screen
This screen shows the time, actual temperature and the heat relay status (On or Off)
High/Low RUN mode screen
This screen shows the time, actual temperature and the heat status of both high and low flame
Pressing the Information button followed by option 1 will show the following display:
This display is shows the target temperature along with the
switching period status.

Override
The Heatmiser IQ+ can be overridden into a day or night condition to allow for any unscheduled operation
of the system. The maximum time that the unit can be overridden will have been set by the installer.
To program an override period
• From the Normal RUN mode
Press the Override button and enter your security code if required.
• Then choose 1) to enter the override mode
• Then select either 1 or 2 to override the zone
ON(1) or OFF(2)
• You are now prompted to enter the length of the override period.
• Should the zone be above temperature, the control will show the
following screen. Remember that the override function only overrides
time and not temperature. This error message will also appear if the
override time programmed exceeds the maximum override setting
• The status screen then indicates the zone has been
put into an override condition.
To cancel an override period repeat the steps above, choosing 2 for
OFF and then reduce the length of the override period to 00
Summer Mode
To enable the Summer mode facility press the Override/Summer button and select 2 for summer.
The control is then put in to the summer mode, which means that the temperature is controlled to the Night
setback setting.
To cancel repeat the above operation.
Date
To display the current time and date:
• Press INFO
• Press 2 for date.
• To cancel, repeat the above operation.
Heater Lockout/Reset
A supply can be wired into the Heatmiser from the heater lockout connection allowing for remote indication
of a fault. Once the fault has been rectified on the heater, pressing RESET on the keypad sends a reset signal
to the heater to clear the lockout status. This feature is highly beneficial on heaters installed out of reach.
Heater Reset (No lockout indication)
On heaters where there is no heater lockout, the Heatmiser can be used to send a reset signal.
To send a Reset signal in the case:
• Press the Info/Reset button
• Press 3 for Reset
The reset relay will be energised for a second.

Manual Summer Fan
Providing the installed heaters are equipped with a summer fan facility, the Heatmiser can enable the fan
to give ventilation in summer months.
• Pressing the FAN key displays the following screen.
• At this point you must press ENTER or if you wish to abort this operation pres the DELETE key.
To disable the fan, repeat the above operation.
If the FAN key does not operate, the fan output is being used to give constant or automatic summer fan
control. This is described later in this manual.
Program Mode
From the Normal (RUN) mode screen, pressing the PROG
button will display the following screen.
Before you can access the Heatmiser you must enter the passcode. This passcode is set to 0000 as a factory
default but may be changed at any time by the user to ensure security. This process is explained under
section 4 (code).
Temp
This section is used to changed the temperature settings.
Pressing 1 for Temp displays the following screen:
• You are now prompted to enter the required temperature for the
DAY periods (EG:22.0). This must be entered as three digits.
• When complete, press Enter
• You are now able to select whether you require frost protection.
Selecting ON enables you to set a NIGHT setback temperature.
• Press Enter when you have set the required night
temperature.
If S.Fan has been enabled, you are prompted to enter the summer fan
temperature. The summer fan temperature is calculated by a differential
setting. For example a differential of 03 means that the summer fan
temperature will be 03°C above the day setting. Therefore there is no risk
of the DAY temperature being higher than the Summer Fan setting.
Data
The DATA section is where you are able to set the daily switching periods. There are 3 switching periods per
day available.
• Press PROG and enter the security code
• Now select 2 to enter the DATA menu.
You can see on screen now that we are prompted to enter the switching
period 1 for Monday. So using 24 hour clock notation, enter the required
start time. (EG: 08.00)
Now press enter to accept the Start time and to move the cursor to the end time setting.
We are able to program the required End time, for example 17.00. Don’t forget to use 24 hour clock notation.
When complete, press Enter to accept the programmed switching time and to move onto period 2 Monday.

Programming further periods
You are now able to program period 2 Monday in just the
same way. Press Enter when complete.
Should you not require all three switching periods, simply leave the
times at HH:MM and this period will be ignored.
At this point press the Enter key to move onto Tuesday’s switching periods.
You are able to enter the switching periods for Tuesday
In just the same way.
Should the switching periods be the same on Tuesday, you can press the COPY button and this copies all of
the switching times from the previous day. So, for example, if you were to press the COPY button on Tuesday
period 1 all of the switching times from Monday would be copied, and then the Heatmiser would move onto
Wednesday.
A screen is displayed to indicate the time have been copied.
To correct any mistakes made, use the DEL Key. If Enter is pressed at any time then
the current settings will be retained.

Engineers Setup
To enter the engineers section, press the program button and enter the Engineers code. (This will be found
on a label inside the Heatmiser. )
A display like the one shown will now be displayed.
OVER (Override)
This section allows you to enter a limit for the override. Enter two digits
(eg:08 hours) and then press enter to accept the setting.
OPTI (Optimisation)
With the Heatmiser Mistral you are able to set whether optimisation is required (Refer to Terms for further
information).
Should you require optimisation select 1 or 0 to disable it.
Selecting NO will return you to the Setup Menu and turns off optimisation. This means the control will switch
the heating ON at the programmed switching time and will not allow for any warm up period.
This is the amount of time the heating system takes to raise the building
temperature by 1.0°C. An average starting point would be 20 minutes
but because the unit is self learning, it will alter itself by 1minute per day
to adjust to the correct setting.
This is the maximum number of hours before the entered switching time
that the unit could come on to raise the temperature. The maximum
setting is 8 hours but an average setting is 3 hours.
CODE
The code section will work as normal and is used to set the User’s code.
SETUP
This section allows us to configure the control, set the required fan mode,
enable or disable the internal sensor and set-up the service mode.
CONFIG (Configuring the Heatmiser IQ+)
During the configuration process you will be asked to select the functionality required for the system being
controlled.
• Press PROG
• Enter the Engineer code
• Select 4 for Setup

CONFIGURING THE HEATMISER IQ+ (ON/OFF TYPE)
PURGE OPTION
You are now prompted to select whether a purge is required.
Selecting N here enables you to bypass the next two displays.
Pre-purge activates relay 3 for the amount of time specified before
the heat relay is activated.
Post-purge will activate relay 3 for the amount of time
Specified after the heat relay has been switched off.
DOUBLE IGNITION
Enabling this option gives the following functionality.
When the heat relay is activated for the first time of each switching time, it will switch off after 30 seconds.
Then after a further 10 seconds the relay is re-energised and will operate as normal.
This operates at the start of every switching period and is used to ensure
that the heater fires when installed in areas where there is a high level
of condensation.
If post purge is enabled, the fan will timeout before the heater re-fires.
PROVING SWITCH
You are now prompted to select whether you have a proving switch
on the system.
When there is a demand for heat, the Heatmiser looks to check firstly that the proving switch is not made.
Relay 3 is then energised giving pre purge if required. The proving switch then makes followed by relay 2
being energised.
When you have completed the configuration procedure you will be returned to the setup menu screen. At
this point you can press RUN to return to the Normal RUN mode or you can continue to program the other
settings by selecting another menu option.
UP/DOWN TEMPERATURE LIMIT
You are now prompted to enter the limit for the Up/Down temperature
keys. With a limit set to 02, you can increase/decrease the set
temperature by 2°C.
