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 set 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 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 - 08.00 the control would be in a DAY condition. Outside of those 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 & Reset is standard on the Heatmiser IQ and allows 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 (i.e.
showing the Time/Day or the Info 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 MODE
There is one main Normal (RUN) mode screen, and one Info Screen on the Heatmiser IQ. These are
explained below:
The Normal (RUN) mode screen shows information such as
Current Time, Current temperature and the relay status.
The Information screen shows the target temperature
along with the switching period.
To view the Information screen, press INFO and select 1 for Information.

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 Summer mode, which means that the temperature is controlled to the
Night Setback setting.
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 this case:
Press the Reset button.
Press 2 for Reset.
The Reset relay will be energised for a second.

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).
1) TEMP
This section is used to change 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 OFF returns you to the DATA menu.
• Selecting ON enables you to select a NIGHT setback temperature.
• Press Enter when you have set the required night temperature,
and then press RUN to return to the Normal RUN Mode.
2) DATA
The DATA section is where you are able to set the daily switching periods. There are 3 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 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 similar to this . . .:
To correct any mistakes made, use the DEL key.
If Enter is pressed at any display then the current settings will be retained.
3) TIME
This is the section used to set the current Time & Day.
• Press PROG and enter security code.
• Then select option 3 for Time.
• The time currently set is displayed on screen along with a
prompt asking for the new time. Simply enter the new time
remembering to use 24 hour clock notation. (EG: 14.23)
• As the Heatmiser IQ does not have a calendar,
the current day must now be set. So for example,
if today is Wednesday press 3.
• The control will then return to the DATA menu.
• Press RUN to return to the Normal RUN mode, you will now notice the correct time and day has
been set.

TECHNICAL INFORMATION – ENGINEERS SET UP
To enter the engineers section, press the program button and enter the Engineers Code. (This will be
found on a label stuck to the facia or on the reverse side of the keypad. This label should be removed
after the control has been commissioned.
A display like the one shown will now be displayed.
1) OVER
This section allows us to enter a limit for the override.
Enter two digits (eg 08, for 8 hours) and then press enter to accept the setting.
2) OPTI
With the Heatmiser IQ you are able to set whether optimisation is required. (Refer to Terms for further
information).
Should you require optimisation select 1 for ON and then continue
to set the following parameters.
Selecting OFF returns you to the Setup Menu and turns off optimisation. This means that 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
O
C. An average starting point would be
20 minutes but because the unit is self learning, it will alter itself by
1 minute per day to adjust itself 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 building up to the
temperature. The maximum setting is 8 hours but an average
setting is 3 hours.
3) CODE
The code section will work as normal and is used to set the User's code.
4) SET UP
