Cooling Parameters Module (5-02) (Optional)

The cooling output (O2) is software selectable with dual alarm models (For

the CN63300, this is referred to as the Second Control Output). This output
operates as an independent cooling output for systems that use heating and
cooling. To enter the Cooling Output Module, the cooling output of the
controller must first be selected in Alarm Module (4-AL). When cooling is
selected, alarm 2 is used for the cooling output.

The front panel indicator A2 illuminates when the cooling output (O2) is

on. Cooling output power is defined as ranging from -100% (full cooling) to
0% (no cooling, unless a heat-cool band overlap is used). See Output Power
Limits in Module 2 for maximum and minimum settings. The same PID
values control both heat and cool.

Cooling Output Cycle Time (CYC2)

A value of 0 turns off the cooling output, independent of cooling power

demand.

CYC2 -

0 to 250 seconds

Cooling Relative Gain (GAn2)

This parameter defines the gain of the cooling band relative to the heating

band. A value of 0.0 places the cooling output into ON/OFF Control mode
with the ON/OFF Control Hysteresis (CHYS) in Output Parameter Module
(2 -OP) becoming the cooling output hysteresis. This may be done
independent of the main output control mode (PID or ON/OFF). Relative gain
is generally set to balance the effects of cooling to that of heating for best
control. Figures 18, 19, & 20, Heat/Cool Operation, illustrate the effect of
different gains.

GAN2 -

0.0 to 10.0

Heat and Cool Overlap/Deadband (db-2)

This parameter defines the area in which both heating and cooling are

active (negative value) or the deadband area between the bands (positive
value). The parameter units are degrees or tenth’s of degrees (depending on
system resolution). If a heat/cool overlap is specified, the displayed percent
output power is the sum of the heat power (O1) and the cool power (O2).

db-2 -

-999 to 9999

When the Cooling Relative Gain is set to zero for ON/OFF Control mode,

this parameter should only be set to a positive value or zero. The Heat/Cool
Operation Figures illustrate the effects of different deadbands.

When using the cooling output, observe the controlled temperature

characteristics. If the temperature remains above setpoint with a sluggish
return, increase the cooling gain. Similarly, if the temperature drops too
