Kanmor Mixing Control 362e Data Brochure page 6

MIXING TARGET TEMPERATURE (MIX TRG)
The MIX TRG temperature is determined from the Characterized Heating Curve settings and the outdoor air temperature. The
control displays the temperature that it is currently trying to maintain as the mixing supply temperature. If the control does not
presently have a requirement for heat, it displays "– – –" in the LCD.
TERMINAL UNITS (TERMINAL)
The control requires the selection of a terminal unit. The terminal unit determines the shape of the Characterized Heating Curve
according to how the terminal unit delivers heat into the building space. The control provides for selection between six different
terminal unit types: two types of underfloor heat, fancoil, fin-tube convector, radiator and baseboard.
Underfloor Heating (Screeded) (U/F1)
U/F1 is a heavy, or high mass, hydronic radiant floor system. This type of a hydronic
radiant floor is embedded in either a thick concrete or gypsum pour. This heating
system has a large thermal mass and is slow acting.
Underfloor Heating (Plated) (U/F2)
U/F2 is a light, or low mass, hydronic radiant floor system. Most commonly, this
type of radiant heating system is either attached to the bottom of a wood sub floor,
suspended in the joist space, or sandwiched between the subfloor and the surface.
This type of radiant system has a relatively low thermal mass and responds faster
than a high mass system.
Fancoil (UNIT)
A fancoil terminal unit or air handling unit (AHU) consists of an hydronic heating coil
and either a fan or blower. Air is forced across the coil at a constant velocity by the
fan or blower and is then delivered into the building space.
Fin-tube Convector (FIN)
A convector terminal unit is made up of a heating element with fins on it. This type
of terminal unit relies on the natural convection of air across the heating element to
deliver heated air into the space. The amount of natural convection to the space is
dependant on the supply water temperature to the heating element and the room
air temperature.
Radiator (RAD)
A radiator terminal unit has a large heated surface that is exposed to the
room. A radiator provides heat to the room through radiant heat transfer and
natural convection.
Baseboard (BASE)
A baseboard terminal unit is similar to a radiator, but has a low profile and is
installed at the base of the wall. The proportion of heat transferred by radiation from
a baseboard is greater than that from a fin-tube convector.
MIXING PUMP OPERATION (MIX PMP)
The Mixing Pump contact (Mix Pmp, terminal 5) closes whenever there is a Mixing Demand and the control is not in WWSD.
During WWSD, the mixing pump is operated based on the EXERCISE setting in the Adjust Menu.
PURGE (PURGE)
After the Mixing Demand has been satisfied, the control can continue to operate the Mixing Pump for a period of time. The
length of time that the Mixing Pump continues to run is an adjustable time setting. This setting allows any excess heat to be
purged out to the heating system. The Mixing Pump continues to run until the Purging time has elapsed or the mixing supply
temperature drops below the MIX MIN setting. This setting should not be used if the mixing system is zoned using either zone
pumps or fast acting zone valves.
SETBACK (UnOccupied)
To provide greater energy savings, the control has a setback capability. With setback, the supply water temperature in the system
is reduced when the building is not used (HOL) or when the building is UnOccupied. By reducing the supply water temperature,
air temperature in the space may be reduced even when thermostat(s) are not turned down. This feature is enabled by setting
the Setback / None DIP switch to the Setback position, and providing either an external signal or an internal override.
Note: HOL does not require the DIP switch = Setback
