e7w Temperature Control related issues
The e7w is not controlling Room Temperature or Fan Speed
Possible Reasons:
➢ The e7w is set to a Room ID, PAN ID and RF Channel that is different than what is configured into the
RF to S5 bus media gateway device (ie PC502) the e7w is supposed to go through to talk to the S5 bus
connected HVAC partner (such as an X47).
Verify the e7w and the PC502 are both set to the same Room ID, PAN ID and RF Channel. If required ,
verify the Room ID, PAN ID and RF Channel set into the e7w is correct and Re-bind the PC502 using the
e7w.
➢ The PC502.4G or other RF to S5 media gateway device used to pass RF messages from the e7w onto
the wired S5 bus connected to the X47 (or other S5 bus connected HVAC controller) is not configured
or installed correctly.
Verify the PC502 or other device responsible for media gatewaying RF to the S5 bus connected to the
HVAC controller is installed and powered and set to the same Room ID, PAN ID and RF Channel as the
e7w. If required , verify the Room ID, PAN ID and RF Channel set into the e7w is correct and Re-bind
the PC502 using the e7w.
➢ The HVAC controller partner to the e7w (such as an X47) is not installed, not connected correctly ,
not powered or not configured correctly.
Verify the HVAC controller is installed and powered , and if S5 bus connected , it is correctly connected
to the same S5 bus as the PC502.4G or other RF to S5 media gateway device that allows RF
communication with the e7w.
It is common to power the Inncom HVAC controller (typically an X47) from the HVAC unit since the
HVAC controller is typically installed inside the HVAC unit. Verify the HVAC unit has power and that
transformer or power supply powering the Inncom HVAC controller is installed and connected
correctly.
Verify the X47 HVAC controller partner was correctly configured via its required I/O Map or
configuration pushed from the EngINN configuration/commissioning tool. Refer to applicable
installation/commissioning documentation.
➢ The HVAC controller partner address used by the e7w is not correct. Anytime you do a
temperature control or Fan speed action on the e7w, it will send a message to the HVAC partner
address defined by the e7w’s “PA” (Partner Address) Parameter. By default, this address is 14, the
standard device address of an Inncom thermostat. However, the HVAC partner address can vary
depending on the installation. Verify the defined e7w HVAC partner address is correct. Appendix 5
covers the e7w PA parameter and how to view/set its value.
➢ An “RF Loop” exists. An “RF Loop” refers to a condition where 2 or more Inncom RF devices set to the
same Room ID and RF Channel are also connected via wired S5 bus. Anytime one RF device receives a
message, it passes the message onto its S5 bus. But then, the other RF device will receive the message
via wired S5 bus and send it out via RF to be seen by the original RF device. This will continue on and
on in a continuous loop and prevent other messages from being sent either RF or S5 bus. The solution
is to NOT connect the orange S5 bus data wire between the 2 RF devices , or disable the S5 Bus
