SPA allows you to adjust the temperature of a single zone. It is equipped with 0-10 V output to modulate the zone damper and a live output for the valve. It is equipped with a blue backlit LCD display and touch buttons for programming time zones and operating temperature.
SPA is a versatile thermostat that allows a single model to control all Sollis hydronic terminals (heating and cooling), the zone valve, if any, and the underfloor system (heating only).
You can enter two daily operating periods for weekdays plus Saturday and Sunday.
The large backlit LCD display shows the current time, the room temperature, and the set temperature.
The device has an additional live contact for enabling a zone valve or heat generator. Regardless of the set time programming, it is possible to manually set the desired temperature at any time.
The chronothermostat can be installed in dedicated flush-mounted boxes or, via adapter, in 3-module flush-mounted boxes.
Both the customized flush-mounting box and the adapters necessary for using the 503 box (not supplied) are supplied with Vision.
The daily-weekly programmer allows you to manage the zone damper in modulation with integral proportional modulation algorithm. The temperature can be set both hot and cold, with two daily switching on and off.
Vision finds its natural application in combination with MultiEasy Plenums with modulating dampers.
