The APP allows to control and program THERMO ICE WiFi from iOS mobile devices. With THERMO ICE APP you can manage, in a easy way, your heating/cooling system from your mobile device: you need a Gewiss THERMO ICE WiFi thermostat on your plant. You can see the current room measured temperature and temperature set point, the HVAC mode (comfort, pre-comfort, economy, off) and a feedback if your heating/cooling system is working or not. You can modify the current and programmed setpoint or the HVAC mode wherever you are. With the APP you can program daily scheduled temperature profile in order to plan the desired temperature at every time of the day or activate the self learning function that, after learning your habits, generates a program in an automatic way.

About

Features
Read full description

GAYA is the new PESS system that guarantees the protection of your premises and people from intrusions, fires, and more. It can also manage automations such as opening gates, doors, shutters, and much more. Using the Gaya app, you can program and manage the system either via cloud connection from anywhere in the world or locally via Bluetooth. In addition to programming and managing the system, thanks to the cloud connection, you can receive PUSH notifications for every event that occurs on the system. In addition to PUSH notifications, you can receive calls with pre-recorded voice messages or text messages by installing the optional 4G GSM module. This module also provides a backup cloud connection over a 4G network. Therefore, any malfunctions on your home Wi-Fi network won't be a problem; the control panel will automatically switch from Wi-Fi to 4G. In addition to Gaya's built-in Wi-Fi, it can also be connected to the cloud via Ethernet with the optional ETH24 module. In this case, we can assign different networks to the Wi-Fi and wired portions (wired network on the home fiber connection and Wi-Fi on a backup 4G router or another network). Gaya can manage up to 80 FLYK PESS series devices, as well as 2 wired inputs and 4 relay outputs, one of which is dedicated to internal/external sirens.
