2 On Room Temperature Increase: As thermostat branch (output) pressure<br />
increases from 3 to 8 psig, N.C. steam valve modulates from open to closed<br />
position. As thermostat branch pressure increases from 8 to 13 psig, N.C.<br />
chilled water valve modulates from closed to open position.<br />
