Control your pool, spa, or heat pump from your phone
DIN500-N is a waterproof WiFi pool heater controller and remote pool heater thermostat for compatible pool, spa, hot tub, gas heater, millivolt heater, heat pump, and cold plunge or ice bath chiller systems. Use the Smart Life app on iOS or Android to turn your heater ON or OFF, monitor water temperature, change the setpoint, and manage heating schedules through the app.
For everyday use, vacation homes, or rental properties, DIN500-N lets you preheat water before arrival and helps reduce unnecessary heater runtime. Instead of investing in expensive proprietary pool automation systems, it gives you practical smart control for many compatible heaters.
What DIN500-N Adds
Control from anywhereManage your pool heater, spa heater, or heat pump remotely using the Smart Life app.
Manual and automatic controlUse Manual Mode for direct ON/OFF control, or Automatic Mode to control heating by setpoint.
Smart schedules and app routinesUse Timer, Delay, Cycle, countdown, Temp Reserve schedules, Tap-to-Run scenes, alerts, and buzzer control.

Wide Heater Compatibility
DIN500-N is designed for a wide range of compatible water-heating and temperature-control equipment, including many gas pool heaters, millivolt heaters, electric heat pumps, spa heaters, cold plunges, ice baths, or water chillers, and popular systems from brands such as Pentair, Hayward, Jandy, Raypak, and others, depending on the equipment's control design.
For flexible installation, DIN500-N uses a two-wire, no-voltage, no-polarity switching connection. These control wires act like a simple dry-contact switch, protecting the heater's control board while allowing connection to compatible remote control, fireman switch, or thermostat circuits. On many newer gas heaters, it can connect to the two-wire remote/fireman switch input. On some older heater systems, it may be used in place of a mechanical thermostat connection, based on the design.
Universal Two-Wire Dry-Contact Control
The DIN500-N uses two no-voltage, no-polarity control wires that act as a simple switch. This makes it suitable for many compatible heaters with remote/fireman switch inputs or thermostat control circuits.
DIN500-N does not power the heater's main electrical load. The heater's own flow switch, pressure switch, ignition control, limit protection, and safety controls still remain part of the heater.
Smart Life App Features
The app provides advanced control features for modern pool, spa, and heat pump automation. Smart Life is the recommended customer setup app, and Tuya Smart may also work as an alternative for customers who already use the Tuya app ecosystem. A standard WiFi network is required for setup.
Use Manual Mode for direct ON/OFF control from your phone.
Use Automatic Mode to control heating based on your selected temperature set point and hysteresis range.
Use Timer, Delay, Cycle, and countdown routines for scheduled or repeating control.
Use Temp Reserve to schedule different temperature targets by time or day.
Create Tap-to-Run scenes for one-tap routines like preheat, stop, weekend use, or vacation mode.
Create Smart Life automations using schedules, DIN500-N measured temperature, city weather data, your location, or the status of DIN500-N or another Smart Life device.
Set temperature calibration, high and low temperature alarms, buzzer control, manual switching, and emergency stop.
Share device access with multiple smartphones for family members, technicians, or property managers.

Common Questions
Will DIN500-N work with my heat pump?
DIN500-N can work with many compatible electric heat pumps, depending on the heater's control design. Check whether your heat pump has remote, fireman switch, thermostat, or dry-contact control terminals.
Can I use Manual Mode for ON/OFF control?
Yes. Use Manual Mode for direct ON/OFF control from the app, or use Automatic Mode to control heating based on your selected temperature set point and hysteresis range.
Can I use DIN500-N with Pentair, Hayward, Jandy, or Raypak?
DIN500-N is designed for many compatible heaters from brands such as Pentair, Hayward, Jandy, Raypak, and others, depending on the heater's control design.
Which app should I use?
Use Smart Life for normal setup and ThermoMart support. Tuya Smart may work as an alternative if you already use Tuya devices.
