Heat pump control with buttons

Other Hardware Home Automation
1

Hi
I'm new to this Arduino and I'm seeing if I can make a control for my heat pump so I have the following buttons
10 degrees
18 degrees
20 degrees
22 degrees
power off
I've messed up a bit with Heatpumpir from GitHub GitHub - ToniA/arduino-heatpumpir: An Arduino library to control split-unit heatpumps over Infrared but I may not quite understand I've got the one called PanasonicRelayControl to work can not just figure out and translate the codes.
the ones I receive with IRrecvDumpV2 look like this:

so I do not know how to conveter and set up the buttons
hope there is someone who can help me

Humm, so by reading the output of your program, I am supposed to figure out the code of the program and then fix the program as per your description? How well do you think that will work?

You could, of course, post the code, in code tags? Please?

/*

This is a project I did for my my friend's summer cottage (he was previously using the MideaRelayControl sketch).
He has an alarm system with some extra relays which can be controlled via GSM SMS messages. With two relays
we can have four heatpump states:

  • relay 1 OFF and relay 2 in any state: heatpump OFF
  • relay 1 ON and relay 2 OFF: heatpump ON, normal heating state
  • relay 1 ON and relay 2 ON: heatpump ON, maintenance heating (FP mode on Midea's remote)

The IR led is driven by a transistor amplifier. I used 2 ohms as the resistor. I might sound
very small, but also the led operates on very short bursts. For example Panasonic uses 2 ohm
resistor for the IR led on its remotes.

could you surround your code w code tags?

I got to work with this code

#include <Arduino.h>
#include <HeatpumpIR.h> // GitHub - ToniA/arduino-heatpumpir: An Arduino library to control split-unit heatpumps over Infrared
#include <Button.h> // Arduino Playground - Button Library

/*

This is a project I did for my my friend's summer cottage (he was previously using the MideaRelayControl sketch).
He has an alarm system with some extra relays which can be controlled via GSM SMS messages. With two relays
we can have four heatpump states:

  • relay 1 OFF and relay 2 in any state: heatpump OFF
  • relay 1 ON and relay 2 OFF: heatpump ON, normal heating state
  • relay 1 ON and relay 2 ON: heatpump ON, maintenance heating (FP mode on Midea's remote)

The IR led is driven by a transistor amplifier. I used 2 ohms as the resistor. I might sound
very small, but also the led operates on very short bursts. For example Panasonic uses 2 ohm
resistor for the IR led on its remotes.
