• If English is selected, sensor types in ˚F (Fahrenheit), PSI (Pounds/Square inch), and
Hg (Inches of Mercury for Vacuum) will be available.
• If Metric is selected, sensor types in ˚C (Celsius), MPa (Million Pascal), and mm
(Millimeter of Mercury for Vacuum) will be available.
• %RH (Relative Humidity) will be available in both options.

Options: Temp.230˚F/110˚C, Pressure: 30PSI/0.25MPa, 100PSI/0.60MPa,
200psI/1 .0Mpa, 300psI/1 .6Mpa, vac . 30hg/760mm, and humidity %rh

• The Sensor Type available options depend on the Standard option selected from the
previous menu.
• This option determines the type of Sensor that can be used. The MC Elite will measure
the input terminals that are associated with the Sensor Type selected. See "Sensor
Type Table" on page 6.

Control Mode

(Only When Sensor Type=Temp.)
Options: Outdoor reset, set point
/<System Startup>/Standard/Sensor Type/Control Mode
SET
• The new MC Elite has two heating logics. Outdoor Reset; varies the system
temperature set
point/target based on outdoor temperature. This selection adds several menu options
to adjust and fine-tune the reset ratio curves: Reset Ratio, Offset, Min Water temp, Max
Water temp, and outdoor Cutoff. In addition, a customized reset ratio curve will be
available for specialized applications.
• Set Point; gives the installer the flexibility of selecting a fixed set point. In this case, the
outdoor Cutoff option will be available only if an outdoor sensor was installed.

Application

(Not Available with Outdoor Reset)
Options: heat-BreakOnrise, Cool-MakeOnrise
/<System Startup>/Standard/Sensor Type/Control Mode/Application
SET
• In Heat-Break-On-Rise mode, the control will start its System relay and modulate the
output when the sensor value is below the Target.
• In Cool-Make-On-Rise mode, the control will start its System relay and modulate the
output when the sensor value is above the Target.

Modulation signal

(MCA Only)
Options: 0-10v, 2-10v, 0-5v, 1-5v, and 4-20mA
/<System Startup>/Standard/Sensor Type/Control Mode/.../Mod.Signal
SET
• The MCA Elite can connect to a variety of modulating outputs that range from voltages
to current.
• Select the Modulation Signal based on the equipment the MCA Elite is controlling.

Modulation target

(MCA and MCP Only)
Options: valve, h/C unit
/<System Startup>/Standard/Sensor Type/Control Mode/.../Mod. Target
SET
• The MCA and MCP Elite controls can modulate either a valve or a Heating/Cooling unit.
When Heating/Cooling unit is selected, a Relay Output option will be available to select
the output relay functionality (See next setting). In addition, a Purge delay option will be
added to the Settings menu. See "Purge" on page 16.
• However, when Valve is selected, the output relay will be assumed to operate a pump.
