1. When an LCI (Lontalk Communication Interface) is installed on a Voyager Commercial VAV unit,
2. The MWU terminate setpoint is identified as NCI (Network Configuration Input)
3. The MWU initiate setpoint is nciSetpoints.occupied heat - 1.5F .

Default Operations

The ReliaTel Refrigeration Module (RTRM) can accept input from any of the following:
Mechanical Zone Sensor Module (ZSM) BAYSENS106-111A, AYSTAT106A-109A.
Programmable Zone Sensor BAYSENS119*, AYSTAT666*Conventional thermostat BAYSTAT036-
038A (or similar).
ICS systems – Tracer, Tracker, VariTrac With each installed device, default modes of operation come
into play, depending on that device's inputs. Following is a summary of functions and defaults.
Table 2. Default operation for Mechanical ZSM (CV Only):
J6 Input/connection
J6-1- Zone Temperature
J6-2 Common terminal for 1-5
J6-3 Cooling Set Point (CSP)
J6-5*- Heating Set Point (HSP)
J6-3&5- No CSP or HSP from ZSM
J6-4- Mode Input from ZSM
J6-6*- Common terminal for 7-10
J6-7*- Heat indication
J6-8*-Cool indication
J6-9*- System indication
J6-10*- Service indication
*these connections are only on certain model ZSM's
Table 3. Default operation for Programmable ZSM:
J6 Input/connection
J6-7- Heat indication from RTRM to ZSM
J6-8- Cool indication from RTRM to ZSM
J6-9- System indication from RTRM to ZSM
J6-10- Service indication from RTRM to ZSM
J6-11- Common
J6-12- Communication
J6-14-24 VAC power
*cool fail indication can occur for several reasons. See diagnostic section for more on this.
