Description
OUTDOOR DESIGN
Typically set to the temperature of the coldest day
of the year. The outdoor air temperature used in the
boiler and mixing heating curves that determine the
boiler target and the mix target temperatures.
MIX DESIGN
The supply water temperature required for the mix
zones to heat the building on the typical coldest day
of the year. Recommendations:
High mass radiant floor = 120°F (50°C)
Low mass radiant floor = 140°F (60°C)
Fancoil or air handling unit = 190°F (90°C)
Copper fin-tube convector = 180°F (80°C)
Radiators = 160°F (70°C)
Low profile baseboard = 150°F (65°C)
MIX TYPE
Select the type of mixing device.
VAR = Variable speed injection pump
FLOT = Floating action motor for mixing valves
0-10 = 0 -10 V (dc) analog signal for mixing valves
4-20 = 4-20 mA analog signal for mixing valves
Note: 0-10 and 4-20 are only available when Boiler
Type = 1 Stage or 2 Stage.
MIX MOTOR
The time that the mix actuating motor requires to
operate from fully closed to fully open.
tekmar actuating motors = 105 sec.
Refer to actuating motor for correct setting.
Note: This item is only available when the Mix Type
is set to FLOT (floating action motor), 0-10, or 4-20.
BOILER TYPE
The type of boiler connected to the control.
1STG = single one-stage on-off boiler
2STG = single two-stage on-off boiler
0-10 = 0-10 V (dc) modulating boiler
4-20 = 4-20 mA modulating boiler
EMS1 = tekmar boiler staging controls
EMS2 = Viessmann modulating boilers with
OpenTherm
Note: Only 1STG and 2STG are available when the
Mix Type is set to 0-10 V (dc) or 4-20 mA.
