Capability, Fan Control, and Occupancy Sensing Capability

19

Pipe No

Selectable number of pipes in the 
system.
Default: 

4.0 Pipes

(2.0 Pipes):

 Limits the number of sequences of operation available 

from 0 to 3, and enables heat/cool operation from the same output.

(4.0 Pipes):

 Allows access to all sequences of operation from 0 to 5, 

and enables heat/cool operation from different outputs.

CntrlTyp

Defines the control output for the 
type of valves used in the 
installation (TEC2026-2, 
TEC2026H-2, TEC2036-2, and 
TEC2036H-2 models).
Default: 

Floating

(On/Off):

 For Normally Open (N.O.) or Normally Closed (N.C.) 

24 VAC two-position valves.

(Floating):

 For proportional three-wire control of 24 VAC floating 

valves.

SeqOpera

Determines the sequence of 
operation.
Default:

 1

(0):

 Cooling Only (Off-Cool). The default is 

Cool

.

.

(5):

 Cool/Heat Four-Pipe and Reheat (Off-Auto*-Heat-Cool). The 

default is 

Heat

.

*   Auto can be disabled with the 

AutoMode

 parameter. When Auto 

is disabled, the default for 

(2) 

and 

(4)

 is 

Heat

.

Note:

Choose the selection option 

(0): Cooling Only

 when using a 

changeover sensor to allow changeover to occur between 

Cooling 

Only

 and 

Heating Only

. Choose the selection option 

(2): Cooling 

and Reheat

 when using a changeover sensor to allow changeover 

to occur between 

Cooling and Reheat

 and 

Heating and Reheat

.

Fan Menu

Sets the Fan Mode options.
Default: 

4

(0):

 Low-Med-High: Three-speed configuration using three fan 

relays (L-M-H). The default is 

High

.

(1):

 Low-High: Two-speed configuration using two fan relays (L-H). 

The default is 

High

.

(2):

 Low-Med-High-Auto: Three-speed configuration with Auto Fan 

speed mode using three fan relays (L-M-H). The default is 

High

.

(3):

 Low-High-Auto: Two-speed configuration with Auto Fan speed 

mode using two fan relays (L-H). The default is 

High

.

(4):

 On-Auto: One-speed configuration, (H) Auto is for Fan on 

demand and On is for Fan on all the time. The default is 

Auto

.

DHumiLCK 

Locks out the dehumidification 
capability (TEC2036[H]-2, and 
TEC2056[H]-2 models).
Default: 

on

(off):

 Dehumidification is locked out.

(on):

 Dehumidification is allowed.

%RH set

1

Sets the dehumidification setpoints 
(TEC2036[H]-2, and TEC2056[H]-2 
models). This parameter can be 
used only if the dehumidification 
sequence is enabled.
Default: 

50.0% RH

Range: 

30.0

 to 

95.0% RH

DehuHyst

1

Sets the dehumidification hysteresis 
(deadband) (TEC2036[H]-2, and 
TEC2056[H]-2 models). This 
parameter can be used only if the 
dehumidification sequence is 
enabled.
Default: 

5.0% RH

Range: 

2.0

 to 

20.0% RH
