NOTE: The following applications require the control pack- ages shown for Function 10, plus ®eld-supplied thermostats as described below.

Night Set Back Heating Ð In the interest of energy conser- vation, it may be desirable to raise a system's cooling set point during unoccupied time periods, whether they occur at night or on weekends, holidays or other occasions. This ap- plication requires a ®eld-supplied dual set point DA pneu- matic thermostat operating on a switched-main pressure supply. The air supply must have 2 pressure levels available. A nor- mally open pilot valve, controlled by the dual thermostat, is also required. The thermostat set point is determined by the supply pressure selected.

VAV Cooling/Separate System Heating Ð A Moduline cool- ing system may be interlocked with a separate hot water heat- ing system and controlled by a common thermostat. This ap- plication requires a ®eld-supplied switched-main pressure supply, a ®eld-supplied dual set point DA/RA pneumatic ther- mostat, a pneumatic switching relay, a pilot valve, and a pneu- matic hot water valve. The summer mode (cooling) or the winter mode (heating) is selected by switching the pneu- matic supply system pressure between high or low pressure ranges. The pneumatic thermostat operates in either the cool- ing mode (DA) or the heating mode (RA) depending on the supply pressure provided. The pneumatic switching relay re- sponds to the pressure level by selecting either the pilot valve and the Moduline cooling system or the hot water valve and the hot water heating system, to match the thermostat mode.

CONTROL SELECTION

Control Index Ð Table 14 summarizes the control func- tions available with 37HS Moduline air terminals. These func- tions are described in detail in the preceding Control Appli- cations section.

Control Packages Ð In order to obtain a desired set of control functions with Moduline air terminals, the correct combination of control packages is required. Table 15 shows the control packages that must be installed on a master unit in order to achieve each function. The control package num- bers correspond to the numbers on the 37HS Price Pages.
