STC-3028 AC 220v Digital Temperature and Humidity Controller AC 220V

STC-3028 – Complete Temperature & Humidity Controller for Incubators & Hatcheries

The STC-3028 Digital Temperature and Humidity Controller is an all-in-one solution for automatic control of both temperature and humidity. With dual relays (10A each) and an AM2320 digital sensor, this controller can independently manage heating/cooling and humidifying/dehumidifying simultaneously. Perfect for egg incubators, hatcheries, aquariums, mushroom farming, tobacco factories, and pharmaceutical storage. Operating voltage: AC 100-240V.

How to Set / কিভাবে সেট করবেন:

1. Set Temperature Start (Heating/Cooling trigger): Long press UP 1 button for 3 seconds → display ① flashes → press UP/DOWN to set start temperature (default 20°C)
2. Set Temperature Stop: Long press DOWN 1 button for 3 seconds → display ① flashes → press UP/DOWN to set stop temperature (default 30°C)
3. Set Humidity Start (Humidify trigger): Long press UP 2 button for 3 seconds → display ② flashes → press UP/DOWN to set start humidity (default 40% RH)
4. Set Humidity Stop: Long press DOWN 2 button for 3 seconds → display ② flashes → press UP/DOWN to set stop humidity (default 60% RH)
5. Reset to Factory Defaults: Long press DOWN 1 and DOWN 2 buttons together for 3 seconds

Incubator Settings Example (ইনকিউবেটরের জন্য সেটিং উদাহরণ):

• For Chicken Eggs: Start Temp: 37.5°C, Stop Temp: 38.5°C (or set heating mode with hysteresis)
• Humidity (Days 1-18): Start: 45% RH, Stop: 55% RH
• Humidity (Days 18-21 – Lockdown): Start: 55% RH, Stop: 65% RH
• Controller will automatically maintain these ranges using connected heater and humidifier.
