10K ZONE CONTROL (MIX 10K = ZoIn)
(See fig. m)
Set MIX 10K item to ZoIn to add indoor temperature feedback
control of multiple mixing zones
• Control of mixing zones can be provided by connecting a
tekmar zone control to the SYSTEMpro 311
• The zone control provides its own internal mix demand to
the SYSTEMpro 311 control
NOTE: In this case, there is no need to provide
an external mix demand. The zone control is capable
of automatically adjusting the MIX TRG temperature
to improve building occupant comfort and
system performance.
10K SLAB SENSOR (MIX 10K = SLAB) (See fig. n)
Set the MIX 10K item to SLAB to add a slab sensor for
temperature control of a single zone mixing system. Power
must be applied to the Mix Demand terminals (1 and 2).
• SYSTEMpro 311 can use a slab sensor to control the actual
slab temperature
• Slab sensor is placed in the slab and connected to Com and
Mix 10K terminals (20 and 21)
• With slab sensor connected, the control will limit the mixing
supply temperature to keep the slab sensor between the
SLAB MIN and SLAB MAX settings
Slab Minimum (SLAB MIN) (See fig. o)
• SLAB MIN sets minimum allowed core temperature of slab
as long as the control is not in WWSD
NOTE: Caution should be used when adjusting SLAB
MIN setting as this may lead to overheating of zone
during mild conditions.
Slab Maximum (SLAB MAX) (See fig. p)
• SLAB MAX sets maximum allowed core temperature of slab
NOTE: If slab is to be maintained at a fixed core
temperature, set SLAB MAX and SLAB MIN items
to the same setting.
