HR variable speed pump ?
Heat Reclaim variable-speed pump selection:
no = 3-way valve is used
yes = variable speed pump is used
hr_flui

water
-
HR condenser fluid
Heat Reclaim condenser fluid type:
0 = water, 1 = brine
hr_eco
off/on
off
-
HR eco mode ?
Heat Reclaim "Eco" mode:
on = fans disabled in Heat Reclaim (Heat Reclaim efficiency priority)
off = fans enabled in Heat Reclaim (chiller efficiency priority)
rev_3WV
no/yes
no
-
HR reverse 3WV cmd ?
Heat Reclaim 3-way valve reversed command:
NO : 0V = close
no = 0V, 3-way valve fully closed
(water flow depends on "Min flow 3wv position" set in the HR_CFG table)
YES : 0V = open
yes = 0V, 3-way valve fully opened
(there is water flow in the condenser and in the customer loop)
HRewtctl
no/yes
yes
-
HR Control on EWT ?
Heat Reclaim control:
no = HR control on water leaving the 3-way valve
(if the sensor is located after the 3-way valve)
yes = HR control on water entering the 3-way valve
(if the sensor is located before the 3-way valve)

Min flow 3wv enable
3-way valve minimum flow setting:
no = Anti-freeze protection disabled
yes = Anti-freeze protection enabled. When Heat Reclaim is not active
and the outside air temperature is low, the 3-way valve will be opened to
its pre-configured position ("Min flow 3wv position").

HR Min water temp
Minimum water temperature in Heat Reclaim mode: If the temperature
drops below this setting, an alert will be raised (10128). HR condenser
heater will be energized (if present), HR mode will be off and the pump will
be turned on.
* Depends on the selected language (French by default).
