Older Models
If the EIM/thermostat date code is smaller (older) than 1546:
• 2.0 or later versions of Prestige IAQ and RedLINK Vision-PRO thermostats can be used if you update the software on the
thermostat.
• The software update page is https://thermostatsetup.honeywell.com/en-US/SoftwareUpdates/Pages/default.aspx
This page has updates for both Prestige IAQ and RedLINK VisionPRO. Prestige is updated via USB stick; VisionPRO is
updated via microSD card.
• Prestige 1.0 models can not be updated.
• The EIM (if used) can not be updated and must be replaced.

NOTES:
— Only two ERMs can be enrolled in a system at one time – one in Boiler mode and one in Compressor mode.
— ERM is not supported by systems using a forced air zone panel, even if the thermostat is wired to the zone panel
or linked to an EIM. (See the FAQ on page 27 for more on this).
— For Boiler applications, the thermostat must be configured for radiant heat.
— ERM will not support series 20 operation in boiler applications unless a relay is used (page 12). When
configured for radiant heat the Y relay shall be off at all times.
— Prestige IAQ always requires a THM5421R EIM. The ERM can be used in conjunction with the EIM for forced air
systems. The ERM would not be used with a Prestige IAQ on heat only systems without fan.
NOTE: The ERM5220R may only be used with the thermostats listed below. Look for this
image on these products.
If you no longer have the thermostat or EIM packaging, verify thermostat model and manu-
facture date are compatible with ERM. The date code of thermostat (and EIM, if used) must
be 1546 or above (more recent). Compatible models of thermostat and EIM are listed in
Tables 1 and 2. If your thermostat pre-dates ERM compatibility, see the info on Older Models,
below .
