The regulator is equipped with an SD card slot. In this option it reads basic information about the card: the
amount of free space and total card capacity.
Note: We are not responsible for any data loss on your memory card. We do not guarantee that the regulator
will work with all memory card models on the market. The regulator supports SD and SDHC up to 8GB capacity.
Archiving
The regulator stores the number of parameters with a frequency of one minute. The history of work is stored in
the internal memory of the regulator. The regulator stores the last 10 days. This data will be lost when the
regulator is not power supplied. Data recording on an SD card allows analyzing them later on a PC.
Service menu
After entering the SERVICE menu, the regulator displays a window to enter a 5-digit password. There are two
levels of permissions to change service settings which have different passwords. The boiler manufacturer's
password has the highest level as it gives access to all parameters of the regulator. The installation password
does not allow saving changes made to parameters of the BOILER submenu, but it is possible to read them.
After entering a special password, the user can reprogram the processor installed in the RUN-TIME MODULE
using an SD card.
BOILER
Minimum temperature
The boiler temperature decrease below the set value blocks the operation of the HW pump, the CH pump
(except when the mixing valve is installed), and the Buffer pump. The aim of this parameter is to protect the
boiler from dewing.
Maximum temperature
This parameter limits the upper temperature of the boiler. Exceeding this value exits the burning phase to feed
or stop the boiler (depending on other settings). The parameter value should take into account boiler inertia,
matching boiler output to installation demands, so that in the extreme situations, after turning off the burning
phase, the boiler temperature increase did not result in exceeding the boiler temperature approved by the
manufacturer (usually 95C).
Critical temperaturę of the boiler
Exceeding the critical temperature of the boiler will trigger the emergency heat discharge process. In that
situation, all pumps are turned off and the mixing valve is opened. The value of the parameter is selected based
on boiler inertia. The maximum temperature parameter and the critical temperature should be set to protect
the boiler against over-heating in extreme situations.
Return protection temperature
Based on the boiler temperature return sensor and the value of the described parameter, the regulator
protects the boiler return from dropping below the set temperature. The return protection function is achieved
by the mixing valve with the actuator. A 4-way valve is required. When the temperature is lower than the set
temperature, the regulator starts closing the valve, which increases the return temperature.
This function
works only when the return sensor is connected . We recommend connecting the sensor when the hydraulic
system without the buffer was built. This is shown in Figure 5. Hydraulic installation diagram without a heat
