External controls with their own 24VAC transformer may •
be used on zones 3-6. Steering relays can be used through
freewatt control module jumpers JPZ3, JPZ4, JPZ5 and JPZ6
(for zones 3-6 respectively). These jumpers are located on
the center of the freewatt control board.
Control board will use 24V power from external A.
transformer attached to that zone when jumpers
are installed across pins.
Control board will use 24V power that board re-
B.
ceives from connector J17 (1 Amp maximum, 24-
30 VAC) if jumper is not installed across pins.
Connect G signal from air handler to zone 4 on freewatt
control module when using ARH-3 with air handler on
smart zone.
Refer to freewatt PLUS electrical schematics for wiring
instructions.
12.7 Circulator Zoned System - ECR ARM-6P
Dipswitch Settings
Priority Switch:
Confi gure ECR ARM-6P for Domestic Hot Water (DHW) •
Priority when freewatt PLUS System includes indirect
hot water tank. Place priority switch to ON position.
Zone 1 is heating priority. Zone 1 calls for heat all
other zones are temporarily deactivated (Priority LED
illuminated), priority switch is ON.
Timer automatically shuts off this feature if priority
•
zone (Zone 1) calls for heat longer than 30 minutes,
allowing all zones to operate. Cycle repeats in 30
minutes until priority zone is satisfi ed.
Match priority switch setting on ARM-6P to priority
•
setting in freewatt control module. Set using laptop
and MINT Software tool.
12.8 Valve Zoned System - ECR AZ-6CP
Dipswitch Settings
Set four AZ-6CP control “Option” switches as follows:
“Zone Valve/Pump Selection Switch” Set to “ON” •
when using Indirect Water Heater on Zone 1. Switch
allows operation of separate water heating “priority”
pump of Zone 1, confi gure for use with indirect water
heater having its own “priority” circulator pump and all
remaining zones are confi gured with single “primary”
circulating pump and individual zone valves. “Zone/
Valve Pump” Switch is in “ON” position for operation
of water heating “priority” pump in water heating
applications of Zone 1. Zone 1 is central heating zone
(no indirect water heater is confi gured) if “Zone/Valve
Pump” switch is “Off”, only Zone 1 zone valve terminals
are energized. Place “Zone/Valve Pump” Switch in
“OFF” position if indirect water heater is not connected
as Zone 1.
IMPORTANT: “Priority Selection Switch” must be •
in “ON” position when “Zone/Valve Pump” Switch
is in “ON” position. Install jumper wire between
terminals 3 and 4 of “Zone 1” output of AZ-6CP
control when setting “Zone/Valve Pump Selection
Switch” in “ON” position,. Jumper not required
when using zone valve (no indirect water heater
with separate “Priority” circulator) on Zone 1.
Wiring see “ Low Voltage Wiring: Primary/Secondary
Piping with Zone Valve and Domestic Hot Water
Priority Circulator”.
Set “Priority Selection Switch” “ON” when using indirect •
water heater on Zone 1. Use switch to set operational
priority to domestic water heating when used with
Zone 1. Switch in “ON” position, call for heat by Zone
1 (indirect water heater) activates “Priority” pump
connecting to indirect water heater other zones will
temporarily deactivate. Temporarily, no space heating
supply in response to any space heating thermostats.
Priority LED on AZ-6CP will illuminate when priority
function is active. After 30 minutes priority is
terminated all zones will operate normally. Water
heating demand of Zone 1 not satisfi ed, 30 minute
temporary deactivation of all other zones will resume
and cycle will repeat. Set “Priority Selection Switch” to
“ON” for water heating priority and “OFF” for no water
heating priority on Zone 1.]
“ZR-ZC Selection Switch”: Set to “OFF”
•
“DPM-2 Selection Switch”: Set to “OFF” •
12.9 Hydro-Air Zoned System - ECR ARH-3 Set-
tings
Priority Switch:
freewatt PLUS • System includes indirect hot water
tank. Confi gure ECR ARH-3 for Domestic Hot Water (DHW)
Priority. Place Priority Switch to ON position. Water heating
zone, is similar to description above for ARM-6P control
Priority operation of Zone 1.
