34 RT-SVD03G-EN
ReliaTel Refrigeration Module (RTRM)
LonTalk Communication Interface (LCI)
1. When an LCI (Lontalk Communication Interface) is installed on a Voyager Commercial VAV unit,
the morning Warmup (MWU) setpoint located on the RTAM board is ignored. The Morning
Warmup and Daytime Warmup setpoints come from the higher priority LCI-R DAC.
2. The MWU terminate setpoint is identified as NCI (Network Configuration Input)
nciSetpoints.occupied heat. The default setpoint is 71F.
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 if no input/connection this happens:
J6-1- Zone Temperature Unit stops
J6-2 Common terminal for 1-5 Unit stops
J6-3 Cooling Set Point (CSP) HSP + 3F if Local Unit Mode is Auto, otherwise Local HSP
J6-5*- Heating Set Point (HSP) Local CSP - 3F if Local Unit Mode is Auto, otherwise, Local CSP
J6-3&5- No CSP or HSP from ZSM 74F CSP, 71F HSP
J6-4- Mode Input from ZSM Auto Changeover with continuous fan
J6-6*- Common terminal for 7-10 LED’s will not function any time
J6-7*- Heat indication
LED will not come on while heating
LED will not flash during heat fail
J6-8*-Cool indication
LED will not come on while cooling
LED will not flash during cool fail*
J6-9*- System indication LED will not come on while unit has power
J6-10*- Service indication LED will not come on when CFS or FFS trips
*these connections are only on certain model ZSM’s
Table 3. Default operation for Programmable ZSM:
J6 Input/connection if no input/connection this happens:
J6-7- Heat indication from RTRM to ZSM
"Heat" will not be displayed while heating
"Heat fail" will not be displayed during heat fail
J6-8- Cool indication from RTRM to ZSM
"Cool" will not be displayed while cooling
"Cool fail" will not be displayed during cool fail*
J6-9- System indication from RTRM to ZSM
Colon (:) will not blink during normal operation
"Test" will not be displayed during TEST mode
J6-10- Service indication from RTRM to ZSM
"Service" will not be displayed when clogged filter switch has tripped
"Service" will not flash when the FFS has tripped
J6-11- Common No display, no communication
J6-12- Communication No communication- "Cool fail" indication
J6-14-24 VAC power No display, no communication
*cool fail indication can occur for several reasons. See diagnostic section for more on this.
