Heatmiser Plus User Manual
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.
Compensation is a system whereby the Heatmiser monitors the Internal and External
temperatures and regulates the flow temperature according to the preset slope setting in the
control. By monitoring the internal and external temperatures the Heatmiser can calculate the
flow temperature needed to maintain the programmed room temperatures.
Pump Overrun To help dissipate the heat from the boiler, a pump overrun time can be set in
the Heatmiser Plus. When enabled, the pump will run on for a number of minutes
(programmable) after the zone has switched off.
Boiler Sequencing The Heatmiser Plus can sequence up to 6 modular boilers providing the
most efficient way of heating a building.
Alarm/Override Inputs The Heatmiser Plus has 8 inputs which can be used as zone overrides
or alarm inputs. When set as an override, the zone will override on/off when the input is made or
broken. The alarm input mode allows the Heatmiser to flash on screen an alarm message when
the input is made.
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’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—18.00 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.

Service Mode
Pressing the program button and then pressing the override button four times will put the
Heatmiser Plus into Service Mode. This activates all relay outputs for 1 hour. Pressing the same
sequence again will cancel this function.
Important Note: When you are using power open/power closed valves it is important that you
observe the wiring instructions at the back of this manual. Failure to observe these
instructions may result in damage to the valve when using the Service mode.
Override
The Heatmiser Plus has an override function. This allows the user to override the programmed
switching times to allow for unscheduled use of the system.
To override the system first make a note of the zone you wish to override.
• Press OVERRIDE and select the PLEASE ENTER THE NUMBER OF
zone you wish to override. YOU WISH TO OVERRIDE (1-7): 01

to override the system.
• When you have finished 1 HEATING ZONE NO1 (20):18 STATUS OR D01
programming the override, you OUTPUT ON
will see on an indication on the
display. In this case the display shows STATUS OR D01, which means the system has been
overridden to a DAY condition for 1 hour. N01 would be shown to indicate the system has
been overridden to a night condition.
To cancel an override. Repeat the steps outlined above, reducing the number of hours to 00.
Holiday Function (On the keypad)
The Heatmiser Plus has a holiday button on the keypad which can be used to shut the entire
system off.
ARE YOU SURE YOU WANT TO SWITCH ON

Configuring the system
The Heatmiser Plus is our multipurpose control and has a wide number of configurations
available. This section aims to guide you through the configuration process.
To configure the Heatmiser Plus follow the steps below;
• Press PROG and enter the configuration code which will be located on the reverse side of
the Heatmiser keypad or alternatively on the Heatmiser enclosure back box.
• When you have entered the code you will be presented with the following screen.
• At this point you are able to begin 1) SYSTEM CONFIG 2) SYSTEM RESET
the configuration process or you !! WARNING!! Read instructions first !!
are able to reset the system back
to the factory defaults.
SYSTEM CONFIG.
• Press 1 for Config
• You are now presented with 5 possible zone types for Zone 1. These zone types are
explained as follows.
<1> OPT <02> COMP <03> HILO <04> BS FIXED
<05>BS VARIABLE ZONE 1 TYPE ? :
1.OPT = Optimiser. The control will automatically calculate the start up time to ensure the
building is warm by the start of the programmed switching time. It does this by monitoring
the internal temperature and adjusting the amount of preheat required.
2.COMP = Compensator. The control will automatically calculate the flow temperature
required to maintain room temperature. By monitoring the internal and external sensor
temperatures, the flow temperature can be increased or decreased to suit demand. This
calculation is worked from a slope factor which can be altered on-screen. The slope factor
is set to 06 as a factory default. In this setting for every 1 degree rise in external
temperature the flow temperature will be decreased by 3 degrees. If the slope factor
is increased to 07 - for every 1 degree rise in external the flow will be decreased by 4
degrees.
3.HILO = This setting gives control over high/low heaters. A high/low differential setting can
be set which is the number of degrees below the required temperature that the high flame
will switch off.
4.BS FIXED = This option is used when you are sequencing boilers and you have a
hot water cylinder or more than one heating zone on the boiler circuit. The control allows
you to enter a fixed flow temperature.
5.BS(VARIABLE) = This option is used when you have only one heating zone on the boiler
circuit and no hot water cylinder. This option gives you the setting to control the minimum
and maximum flow settings as well as the slope factor which is mentioned under
Compensation above.
