ProMIX™ 101 Radiant
Installation and Operating Instructions
General Description
The ProMIX™ 101 Radiant Reset
Control provides closed loop control of
water in a secondary (radiant) loop of a
heating system, based on outdoor air
temperature and design temperature
settings. It also provides protection
against boiler condensation by monitor-
ing and anticipating the boiler return
water temperature. This control is
designed specifically for radiant heat-
ing but is compatible with other types of
hydronic heat distribution systems
where the use of a weather responsive
control is desired.
Features
•
Provides outdoor reset control using a 3-way proportional valve in familiar plumbing configu-
rations.
•
Eliminates the need to analyze and select complex reset ratios – just set the design tempera-
tures.
•
No guessing about current conditions – the outdoor and radiant loop temperatures are
displayed continuously, along with the secondary loop setpoint.
•
Efficient use of boiler and circulator operation – only turned on to meet heating demands
•
Helpful test mode for system setup and diagnostics.
