THE CORRECT FIRMWARE FOR
The SmartTimer solution is a highly advanced timing and thermal control solution.
- Extremely accurate time keeping by using a high quality DS3231 real time clock.
- Internet time synchronisation to ensure accurate time.
- WiFi connectivity for ease of access
- Web control. The system is easily controlled via a website running on the device.
- 30A / 250VAC relays for high power applications like geysers or pool pumps.
- 20 programable timer settings.
- Each timer can be set with a desired target temperature (optional)
- Away / Holiday mode. Skip all timers during the period you set when you are away.
- E-mail alerts when issues are encountered such as loose wiring (optionally enabled)
- Works with digital temperature probes based on DS18B20 or slightly less accurate alalog 10K NTC thermistors.
- Overheat protection.
- Probe break detection.
SmartTimer can be used as a control solution for various applications. Some uses include:
- Geyser management
- Pool pump management
- Lighting controller
- General purpose timer or switch
- Operating voltage 230VAC / 50HZ.
- Main Relay contact rating 30AMP (Max 4KW).
- Secondary relay contact rating 30AMP (Max 4KW). (optional)
- Operating voltage range 160V – 250V AC.
- Temperature setting ranges 25 – 84°C.
- Maximum temperature 85°C.
- Heat failure – when increase at a rate of less than 4°C per hour.
- Thermal Cut-out 90° C
- Temperature accuracy dependent on probe technology. NTC typically ~2%, DS18B20 typically ~0.5%
- Temperature calibration setting
- Temperature probe failure detection.
- Temperature probe range for geyser is -30 to + 130° C.
