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
