PUFFER CONTROL
The purpose of the LSP-PC1-WiFi controller is to
effectively control the heating of the puffer tank.
The controller has two temperature sensors and
controls a pump. Based on the temperatures
measured in the fire place and the puffer tank, as
well as the set parameters, it controls the pump
and assures the user that the system works
safely and efficiently. The controller is configured
using our smartphone or a laptop connected via
WiFi.

Description
The Puffer Control controller is designed to control the efficient heating of
the puffer tank by controlling the pump on the closed water system of the
fireplace and the puffer tank and by measuring the exact temperature in them.
Compared to the previous version, the innovation is the configuration from the
smartphone and the possibility for the system to send a an alarm meassage
about possible errors. The device has two temperature measuring inputs. Both
sensors are Pt1000, one measures the temperature in the boiler and the other in
the water tank. The controller has one output that operates the circulation pump.
The input voltage is present on this output, which can be 150V - 240V AC.

Display
By default, the temperature displayed on the display alternates between
the temperature of the fire place and the tank every 5 seconds, which can be
distinguished by the appearance of a dot.
In the case of an error, the active error code appears on the display, which is
detailed in the error indications chapter. (When connected to the device with a
phone or laptop, the error signals can be seen online, together with an
explanation.)
Button 1
The main function of the push button is to start the pump when pressed. As
long as the button is pressed, the pump is active, when it is released it turns off. It
can be operated at any time by pressing the button, regardless of operating
mode, it can also be used to test the operation of the pump.
Another function of the button is to stop the alarm. When pressed, the sound
signal stops, only the light signal remains.
Button 2
By long pressing button number 2, we can turn on WiFi on the device, if it
has been turned off under the network settings tab.
Also, with this button, we can reset the controller, the process can be found on
the "Restore factory settings" page.

The controller comes ready-to-use from the factory and provides safe control of the
given system immediately after connection. In addition, personalization is possible, which
can be carried out on the device through the Wifi connection of a smartphone or a laptop.
To access the settings, use your device to find the Puffer_control WiFi availability and
connect to it.
Password of the wifi: password
After a successful connection, by scanning the QR code on the device, the main
page of Puffer Control opens in our browser or we enter the following IP address in the
address bar of the browser (e.g.: Chrome/Google/Safari): 192.168.4.1
If the browser has successfully opened the main page, here we can see the main
data about the system, such as the current temperatures, the state of the pump, and from
here we can choose between the group of parameters to be modified. It is possible to
change the control (Setup) and network parameters (LAN Setup). *
Also, here is the firmware version (lower right corner) and the icon for the manual
(upper right corner).
Attention! Internet access is required when trying to access the manual.
Therefore, it is necessary to disconnect from the controller and provide Internet access.

* By default, the subtitles are displayed in English. The language can be changed by following the
steps described in the chapter „Changing the language”.

Start Temperature: specifies the minimum temperature value of the fire place from which
the control starts. The unit of measurement is degrees Celsius.
Differential Temperature: specifies how many degrees the water in the fire place must be
higher compared to the tank in order for the circulating pump to start. The unit of
measurement is degrees Celsius.
Motor Overrun Sec: we can set the pump running time after the temperatures have
equalized so that the hot water does not get stuck in the pipes. The unit is seconds.
Display Time Internal Temp Sec: the value measured by the two sensors alternates on the
display and with this parameter we can set how many seconds the temperature from the
puffer is displayed. At this value, a dot appears on the display. The unit is defined in
seconds.
Display Time External Temp Sec: the value measured by the two sensors alternates on
the display and with this parameter we can set how many seconds the temperature from the
fire place is displayed. The unit is defined in seconds.
Low Temperature: if the temperature in the system falls below this value, the controller
starts the pump to circulate the liquid to prevent freezing. This value must be determined in
such a way that there is no danger of freezing.
Low Temperature Hysteresis: this value determines by how many degrees the system
must warm back from the value specified in the Low temperature parameter, in order for the
danger of freezing error signal to disappear and the pump to stop.
Dangerously High Temperature: this is the value that, when the water tank temperature is
reached, the controller sounds an alarm and the Error LED lights up. Together with these,
the pump also comes into operation. Furthermore, if the email notification is set, the
controller will send the error signal to the specified address. Its unit is degrees Celsius.
Dangerously High Temperature Hysteresis: the Dangerously High Temperature and the
difference of this value gives the value where the sound signal stops, but the Error LED and
the pump work.
Overheating Temperature: if the temperature of the system has reached this value, the
Error LED will light up and the pump will start. The controller also sends a notification if the
notification sending function is activated.
Overheating Temperature Hysteresis: the value given by the Overheating Temperature
and its difference is the point below which, when the temperature of the fire place drops, the
controller stops the alarm and the pump.

Settings
Default button: by clicking this, we can reset the control parameters separately to the
factory state. When you press it, the system will ask if you want to execute it for sure.
Load button: by pressing it, we can read the currently loaded parameters. After saving, we
can use this to test whether the changes have been saved.
Save button: with this button we can save the changed parameters. If we changed one of
the parameters, we have to press it so that the desired values are stored. After pressing it, a
window will pop up asking if you are sure you want to save the changes.
Logout button: we can use this to return to the home screen. After clicking on it, you will be
asked to confirm whether you really want to exit the settings and save the changes.
Furthermore, when pressed, the WiFi communication of the device will restart, after which it
is possible that we have to reload the page.
There is an info icon next to each text box, which helps you
understand the given parameter.

LAN Settings
Here we can change or reset the network parameters of the controller. For easier
navigation, the menu is divided into 5 parts. You must enter a username and password to

Wifi configurations
Here we can connect the controller to our own home Wi-Fi network, setting the appropriate
parameters. For this, we need to tick the Enable window.
We can search for our network with the Scan button, and then enter the password of our
network in the Wifi password field.
By checking DHCP, we can access the controller automatically, without entering the
following IP address and other datas.
Save with the Logout, then Save and Exit button so that the controller can function
properly. It is absolutely necessary to restart the Wi-Fi communication, which is
automatically performed by the controller.
Attention! Once the controller has been connected to our own network, it can only be
accessed via the Puffer_control wifi network at the address http://puffer.local.
