-## 🎯 What You'll Achieve
-
-This guide walks you through creating a fully functional climate entity in Home Assistant that can:
-
-- ✅ Control target temperature
-- ✅ Turn the heat pump on/off
-- ✅ Monitor real-time status
-- ✅ Integrate with automations and dashboards
-
-## 🧩 The Solution Overview
-
-We're upgrading from basic Modbus sensors to a proper climate entity by:
-
-1. **Installing** `hass-template-climate` from HACS
-2. **Configuring** Modbus sensors in `modbus.yaml`
-3. **Creating** a climate template in `configuration.yaml`

-## ⚡ Hardware Installation
-
-> **⚠️ Safety First**: Have a licensed electrician handle the 240VAC connections!
-
-### Step 1: Power Supply Installation
-
-- Install appropriate PSU using available spade terminals inside the main HWS cover (circled in green in images below)
-- Follow local electrical regulations
-
-### Step 2: EW-11A Connections
-
-**📍 Pin-out Reference** *(left to right when looking down at screws)*:
-
-```
-Pin 1: Black  → RS485A from heater
-Pin 2: Grey   → RS485B from heater  
-Pin 3: Red    → VCC (5-18V DC)
-Pin 4: Black  → GND from DC supply + Yellow GND from heater
-```

-
-### Step 3: RS485 Wiring
-
-- Locate the service connector outside the main panel (circled in red in images below)
-- Connect RS485 wires to the EW-11A 4-pin connector
-- *Tip*: You can either remove pins for direct termination or use jumpers

-## 📡 EW11-A Configuration
-
-### Initial Setup
-
-1. **Connect** to WiFi network `EWxxxxx` (based on MAC address)
-2. **Browse** to `10.10.100.254`
-3. **Login** with username: `admin`, password: `admin`
-
-### Serial Port Settings
-
-Only the following should need changing:
-
-```
-Baud Rate: 9600
-Flow Control: Disable
-Protocol: RS485
-```
-
-### Communications Settings
-
-Only the following should need changing:
-
-```
-Socket Settings → Local Port: 502
-```
-
-### WiFi Configuration
-
-1. **System Settings** → Change WiFi mode to `STA`
-2. **Scan** for your network and enter credentials, OR manually enter:
-   - STA SSID: `your_network_name`
-   - STA KEY: `your_wifi_password`
-
-### Optional: Static IP Setup
-
-```
-WAN Settings:
-├── DHCP: Disabled
-├── WAN IP: <IP address of your choice>
-├── Subnet Mask: <as per your network>
-├── Gateway: <your router's IP>
-└── DNS: 8.8.8.8 or your preference
-```
-
-3. **Submit** and **restart** the EW11-A

-## 🏠 Home Assistant Configuration
-
-### Phase 1: Install Template Climate
-
-1. **HACS** → **Integrations** → **⋮** → **Custom repositories**
-2. **Add**: `[https://github.com/jcwillox/hass-template-climate](https://github.com/jcwillox/hass-template-climate.git)`
-3. Find the repo in HACS and **Download**, then **restart** Home Assistant
-
-### Phase 2: Modbus Configuration
-
-- **Place** the provided `modbus.yaml` in your HA config folder
-- Update the **host** value in `modbus.yaml` to the IP address you have set for the EW-11A (or determine the DHCP address it has)
-- This replaces basic climate entities with proper target temperature sensors
-
-### Phase 3: Climate Template
-
-- **Add** the climate template configuration to your `configuration.yaml`
-- This creates the final climate entity with full control capabilities
