Control electronic control panel

TECHNICAL TASK

CONTROL PANEL SIGNATURE UNIT (v1.0)

1. Purpose of the product

Design an embedded premium control panel for the unit that:

• intuitively controls:

• lighting

• climate

• sound

• atmospheric scenarios

• fire (pellet stove)

• has a minimum number of controls

• looks like a luxury tactile object, not a technical panel

2. Product architecture

The panel consists of 3 levels:

2.1. Technical base

• internal mounting plate (recommended aluminum 3 mm)

• all electrical components

• controllers / relays / terminals

• service access

• quick-connect connections for sound + light + climate, thus 3-4 quick-connects

2.2. User interface

• knobs (rotary controls)

• toggles

• scenario buttons

• 3 analog indicators

2.3. Finish faceplate

• material: brass (2 mm)

• CNC / laser cut

• engraving

• installed after assembling the technical part

3. Functional blocks

3.1. Light

Channel 1 — internal lighting

• 1 dimmer

• smooth adjustment

• load: up to 500 W

Channel 2 — external lighting

• 1 dimmer

• smooth adjustment

• load: up to 500 W

Automatic logic (external light)

• does not turn on in daylight (light sensor)

• operates in the evening

• automatically turns off after 00:00 / 01:00 / 02:00

• manual dimmer = correction

3.2. Climate

Interface

• 1 knob (rotary)

• digital display

• no modes for the user

Labeling:

divisions

Logic

The system controls only:

• air conditioner (main control)

• does not program the pellet stove

Algorithm

setpoint > room temp → heating demand

setpoint < room temp → cooling demand

Heating demand:

• air conditioner can operate in heating mode (if allowed)

• or does not operate (if the stove is active)

Cooling demand:

• air conditioner ON

• pellet stove OFF / blocked

Restrictions

never:

stove + air conditioner (Cool) simultaneously

Additionally

• hysteresis 0.5–1°C

• delay in turning on (anti-frequent switching)

3.3. Pellet stove (FIRE)

Status

• has its own built-in controller

• has its own weekly timer

• operates autonomously

Integration into the panel

Mandatory:

• separate toggle:

FIRE

Toggle function

ON → allow / start the stove in manual mode

OFF → turn off / prohibit

Important

• the panel does NOT duplicate:

• weekly programming

• power modes

• stove menu

Priorities

FIRE ON → prohibit cooling

Additionally

window sensor, if the window is open - prohibit Cooling

3.4. Sound

• 1 knob (volume)

• press function = mute

• source: Bluetooth / predefined scenes

3.5. Scenarios

3 buttons:

ROMANTIC

SPA

LOUNGE

Each scenario activates:

• light (preset)

• brightness level

• music channel youtube / source

UX logic

• knobs = correction

• scenario does not “break” from rotation

3.6. Analog indicators

Mandatory:

• temperature (room)

• humidity

Optional:

• CO2 (if there is an aesthetic solution)

4. Electrical part

4.1. Dimmers

Required:

• 2 independent channels

• each up to ~500W

• compatibility with LED (no flickering)

• power reserve (20–30%)

4.2. Climate

Need to determine:

• type of air conditioner control:

• dry contact / IR / other

• temperature sensors

• basic controller logic

4.3. FIRE

• stove activation interface:

• dry contact / external enable (depending on the stove model)

4.4. Automation

• light sensor (lux)

• timer (night mode)

• basic scenario logic

5. Design

5.1. Base

• aluminum mounting plate

• threaded inserts

• rigid geometry

5.2. Mounting

• remote stands

• service access

• disassembly without damage

5.3. Faceplate

• brass 2–3 mm

• precise holes

• engraving

6. Design

Style

• yacht / boutique / aviation

• warm premium

• without “smart home with tablet”

Materials

• brass

• walnut (optional)

• black scales

Tactility

• knobs with resistance

• toggles with a clear click

• premium buttons

7. UX principles

minimum controls

maximum sensation

no instructions

8. What the engineer must deliver

8.1. Architecture

• module diagram

• component placement

8.2. Electrical diagram

• power supply

• dimmers

• climate

• FIRE

• scenarios

8.3. Logic

• climate

• priorities

• conflict blocking

8.4. Drawings

• dimensions

• holes

• mounting

8.5. BOM

• all components with models from ALIBABA
