Appendix C - VCB-X LON Parameters

SNVTs for the VCB-X Controller

Binary Output SNVTs are SNVT_lev_disc

all other SNVTs are SNVT_count_inc_f

Parameter Name Object Description

Limits

Modulating

Heating

Position

MdHtPos Analog

Output

Current

position of the

modulating

heating signal

(hot water or

SCR heat).

Missing

MODGAS

Module

MisMDGAS Binary

Output

Alarm that

indicates that

the MODGAS

module is not

communicating

with the VCB-

X Controller.

Warm-Up

Return Air

Target

Setpoint

WmupTg Analog

Input

If conﬁ gured,

upon entering

the

occupied mode,

the Warm-up

Demand will be

activated if the

return air tem-

perature is one

degree below

this setpoint.

50 90

Occupied

Cooling

Setpoint

OcpClSt Analog

Input

If the control

temperature

rises one degree

above this

setpoint, the

control will ac-

tivate the cool-

ing demand. If

the control

temperature is

the Supply Air

Sensor, then the

cooling demand

is always

active.

1110

Occupied

Heating

Setpoint

OcpHtSt Analog

Input

If the control

temperature

drops one

degree below

this setpoint,

the control

will activate

the heating

demand. If the

control

temperature

is the Supply

Air Sensor, then

there is no

heating

demand.
