1. Heatmiser Senior Keypad
Soft Keys
The Heatmiser Senior features “soft keys” which can be seen above down each side of
the LCD. If you have used a cash machine, you will be familiar with soft keys The benefit
of soft keys is that the button text is displayed on the LCD and is constantly changed
as you use the control. This removes the need for dual purpose buttons which can be
confusing.
Navigating the Zones
Pressing the Left and Right arrow keys allows you to scroll through the zones set-up on
your system.
Display Back Light
To assist with programming the system, the backlight is permanently on.
2. 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
comfort level. 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.
The Heatmiser Senior only optimises on the 1st switching level of each day.
Compensation is a system whereby the Heatmiser monitors the internal 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 for each zone. When enabled, the pump will run on for a number of minutes
(programmable) after the zone has switched off.
Alarm/Override Inputs: The Heatmiser Senior has 5 inputs which can be used as zone
overrides or alarm input. When set as an override, the zone will override on/off when the
inputs is made or broken. The alarm input mode makes the Heatmiser Senior flash an
alarm message on screen 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)
Rate of Change is the time it takes to raise the building 1ºC The factory default for this
setting is 20 minutes but the control will automatically adjust this according to the fabric
of the building.
3. Initial Set-up Procedure
This initial set-up guide has been designed to help you set-up the control to suit your
installation.
When setting up the Heatmiser Senior you must first set-up the Boiler zone and then any
other zones thereafter.
Apart from the Boiler zones, there are 4 other types available;
Opt: 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.
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 03 as factory default, which means that for every 1ºC rise in outside
temperature the flow temperature is decreased by 3ºC.
Timer: In this mode, the Heatmiser will simply work to the programmed times – and is
not dependant on any temperature settings.
Vent: In this mode, the Heatmiser works in reverse to a normal heating zone. In other
words, the output is active when the actual temperature rises above the programmed
temperature.
Begin Here . . .
• To run the set-up procedure, press Program, enter the Engineers Code of 6343
and press OK.
• Select Initial Set-up
• Confirm that you wish to proceed with the set-up routine
Note: This will delete all previous set-up data
