[3] The minimum pump revolution setting [pump min]
To set the minimum pump revolutions select menu item [3] and press the ‘reset’ key to confirm. The value may then
be changed by using the ‘+’ and ‘-’ keys. Confirm the selection by pressing the ‘menu’ key.
[4] The maximum pump revolutions setting [pump max]
To set the maximum pump revolutions select menu item [4] and press the ‘reset’ key to confirm. The value may then
be changed by using the ‘+’ and ‘-’ keys. Confirm the selection by pressing the ‘menu’ key.
[5] Setting the fixed point of a mixed flow circuit.
If the mxing valve controller MR03 is connected to the Micromat EC then menu item [5] may be used to set the fixed
point for the mixed circuit weather compensation curve. The fiexed point may be adjusted from -20°C up to 20°C at
an outside temperature of 20°C.
[6] Service [Service In]
To reset the sevice interval back to 365 days select menu item [6] and press the ‘menu’ key twice‘. this will remove
the service request from the display.
If a servicing is carried out before the service interval has expired, and if no service request appears on the display
then menu item [6] must still be reset to 365days by pressing the ‘menu’ key twice. If no service request is required
to appear on the display then set the number of days in menu item [6] to OFF (<1)
[7] Pump Continue [Pump ____]
If a pump run-on time is required, then set this parameter to [ON]. The default value for this parameter is [OFF]
[8] ECO and ECO PLUS Operation [ECO+]
Use this parameter to set ECo or ECO+ operation.
In ECO PLUS operation the Micromat EC pump regulates a temperature differential of 20K (10K for underfloor
heating) as long as this is possible. This gives the best fuel consumption figures.
In ECO operation the temperature differential is regulated only if the return temperature rises to over 50°C. For lower
temperatures the pump works at full capacity. This mode of operation will also give very good fuel consumption.
ECO operation is recommended if individual rooms do not get warm enough and hydraulic balancing is not possible.
[9] Domestic hot water pump run on time. [Postrun HW]
The run on time of the DHW charging pump is set in parameter [9]. THis must be set to 0 if the DHW is controlled
using a 2 way 3 port diverting valve. The adjustment range of this parameter is 0 up to 5 minutes wth adjustment
steps of 1 minute.
[10] Heating circulating pump run on time. [Postrun CH]
The run on time for the circulating pumps are set in parameter [10]. The adjustment range is 0 up to 20 minutes with
adjustment steps of 1 minute.
[11] Minimum load [Min Power]
The minimum boiler load is set in parameter [11] . The adjustment range is min boiler output up to max CH.
[12] Maximum load for heating operations [Max Power]
The maximum boiler load is set in parameter [12]. the adjustment range is min. boiler output up to 100%.
[13] Function no. [Function no.]
In this parameter the installation codes may be entered (see last column of the tables on pages ______) These
codes are used to set up the boiler controls and the type of heating required.
[14] Back [Back]
When this parameter is on the display pressing the ‘menu’ key will exit the installation pop up menu.
