1 of 20 © 2009 D 360 - 03/09
The Mixing Control 360 is designed to control the supply water temperature to a hydronic system in order to provide outdoor reset or
setpoint operation. The control uses a floating action mixing valve to regulate the supply water temperature, while protecting the boiler
against flue gas condensation. The control has a Liquid Crystal Display (LCD) to view system status and operating information.
Additional Functions Include:
Quick Setup for easy installation and programming of control
User comfort adjustment to increase or decrease building space
temperature
Advanced settings to fine-tune building requirements
Boiler Control for improved energy savings
Powered mixing system pump output
Optional indoor sensor for room air temperature control
Test sequence to ensure proper component operation
Setback input for energy savings
120 V (ac) power supply
