Smart GSM Control – SIMplyMAX-P03 Relay

This versatile remote control relay, equipped with a GSM module, is an ideal solution for both professionals installing automation systems and end-users looking for a simple way to remotely manage devices. SIMplyMAX-P03 combines the functions of a temperature controller and ON/OFF control capabilities, offering flexibility and ease of use. The device allows you to monitor and control temperature and the status of connected devices from anywhere with GSM network access.

Functionality and application

The SIMplyMAX-P03 relay is a two-state temperature controller that allows remote temperature management via mobile phone. It can be used in a wide range of applications, such as:

• Heating: Temperature control in homes, apartments, greenhouses or utility rooms.
• Cooling: Managing cooling systems in server rooms, warehouses or other facilities requiring precise temperature control.
• Alarm systems: Notifications when temperature thresholds are exceeded or events are detected at the input.
• Remote device control: Turning on and off lighting, pumps, heaters or other electrical devices via SMS.
• Monitoring: Monitoring the operating status of devices and receiving notifications of any failures.

Flexible configuration and ease of use

The relay configuration is done using dedicated software on a PC via USB port or directly via SMS commands. The user has full control over the device settings, such as:

• Controller operating modes: Heating or cooling.
• Temperature control range: -30°C to 65°C with adjustable hysteresis (0-10°C).
• Temperature alarms: Setting minimum and maximum temperature thresholds with SMS notifications to 5 phone numbers.
• Anti-freeze function: Automatic activation when the temperature drops below a set threshold.
• Relay outputs: Configuring outputs to control various devices (ON/OFF, pulse).
• Inputs: Selecting the option to trigger an SMS message (signal appearance/disappearance).

Thanks to this, the relay can be adapted to the individual needs and requirements of each user. Operation in the GSM 900/1800 network guarantees reliable communication without SIMLOCK – an active SIM card from any operator operating in Poland is sufficient. Protection class IP20 ensures safe use under normal operating conditions. Mounting on a 35mm DIN rail facilitates integration with existing electrical infrastructure.
