In addition to using conventional thermostats to provide a mixing demand as described in Section B1, the control can use a
number of other methods to provide a mixing demand.
10K INDOOR SENSOR (10K = INDR)
Set the 10K item to INDR to add an indoor sensor for temperature
control of a single zone mixing system. The indoor sensor is
connected to the
Com and 10K terminals (12 and 13). In addition,
power must be applied to the Mix Demand terminals (1 and 2)
as described in section B1. With the indoor sensor connected,
the control is able to sense the actual room temperature. With
this information, the control prov ides a more constant water flow
through the mixing system. At the same time, indoor temperature
feedback fine tunes the supply water temperature in the mixing
system to prevent over heating or under heating. To adjust the
room temperature for the mixing zone, use the ROOM
Occupied or
UnOccupied setting in the Adjust Menu at the control.
External UnOccupied
An external signal can place the control into an UnOccupied mode. Any time the
UnO Sw (14) and the Com (15) terminals are shorted together, the control operates
in the UnOccupied mode. When in the UnOccupied mode, the UnOcc segment is
displayed in the LCD. The control adjusts the supply water temperature based on
the
UnOcc settings made in the control.
Internal Overrides
The control has a number of setback overrides that are selected through the Schd
Menu. These setback overrides have priority over any external setback signal. Any
time an override is in effect, the
Ovr segment is displayed in the LCD.
Temporary (TEMP)
If a temporary override is selected, the control operates in the selected
override mode for 3 hours. Once completed, the control reverts to the previous
operation.
Permanent (PERM)
If a permanent override is selected, the control operates in the selected override
mode until a new override is selected.
Holiday (HOL)
If the HOL override is selected, the control operates with a fixed WWSD of 62°F
(17°C) and a fixed room temperature of 62°F (17°C).
BOOSTING (BOOST)
When the control changes from the UnOccupied to the Occupied
mode, it enters into a Boosting mode. In this mode, the supply water
temperatures to the system are raised above their normal values
for a period of time to provide a faster recovery from the building’s
setback temperature. The maximum length of the boost is selected
in the user interface.
Typical settings for the Boost function vary between 30 minutes and two hours for a building that has a fast responding heating
system. For a building that has a slow responding heating system, a setting between four hours and eight hours is typical.
After a
Boost time is selected, the setback timer must be adjusted to come out of setback some time in advance of the desired
Occupied time. This time in advance is normally the same as the BOOST setting. If the building is not up to temperature at the
correct time, the BOOST setting should be lengthened and the setback timer should be adjusted accordingly. If the building is
up to temperature before the required time, the BOOST setting should be shortened and the setback timer should be adjusted
accordingly. If the system is operating near its design conditions or if the supply water temperatures are being limited by settings
made in the control, the time required to bring the building up to temperature may be longer than expected.
SOFT START (SOF STRT)
The SOF STRT function allows the control to slowly ramp the water temperature up to the required supply temperature. By
allowing the temperature in the system to be adjusted slowly, the control reduces any thermal expansion noises and stresses
that may be caused by a quick change in supply water temperature.
