Operation & Dip Switch Settings:
General Operation:
When any thermostat calls for heat,
the appropriate circulating pump is energized, the red light goes on and the
boiler end switch relay and AUX circulator relay(s) are energized.
Expansion Connections:
Set dip switch (#1) to MASTER on the
switching relay
that is designated as the priority zone control. Set all other daisy chained zone
controls to EXPANSION.
Using thermostat wire (18-22 gauge) connect between
terminals 1, 2, 3 on the master control to the corresponding 1, 2, 3 on the
expansion
zone control(s). Zone controls may be daisy chained up to 20 Taco
zoning panels using
any combination of SR and ZVC controls (120 zones if all
are 6 zone panels).
Priority Operation:
When the priority dip switch (#2) is set to ON and the
priority
zone (zone 1) is actuated, all other zones will stop operation until priority zone
is satisfied. When not switched to priority, all zones will
operate independently.
More adjustments are available when using the eLink mobile app.
Priority Protection Operation:
If the priority zone calls continuously for more
than one hour, power
is returned to all the other zones, allowing each zone to
function independently. Once the priority zone is satisfied, the control's auto-
reset is
activated, and the priority zone is again allowed to have priority for up
to
one hour starting from when it calls next.
Primary Pump Operation:
When the dip switch (#3) is set to OFF, the primary
circulating pump output will energize when any zone calls for heat,
except the
priority zone. When the dip switch is set to ON, the primary circulating pump
output will energize when any zone calls for heat.
Post Purge Operation:
When the dip switch (#4) is set to ON, the priority
zone output will stay energized for 2 minutes after its thermostat or aquastat is
satisfied, but not operate the boiler. More adjustments are available when using the eLink mobile
app.
Pump Exercise Operation:
When the dip switch (#5) is set to ON, the solid
state timer cycles all the
circulating pumps that are attached to the
Switching Relay to run for 30 seconds every 2
weeks. More adjustments are available when using the eLink mobile app.
Low Limit (ZC) Operation:
When the dip switch (#6) is set to ON and the
boiler drops below the
set low limit (terminal ZC connected to boiler), all zone circulating pumps will stop. When the boiler
rises above the
set low limit, the zone circulating pumps are allowed to operate.
AUX 1; ZR /Circulator Output:
The AUX 1 output is energized when any zone calls for heat.
More adjustments are available when using the eLink mobile app.
AUX 2; Primary Circulator Output:
The AUX 2 output follows dip switch setting # 3 listed above.
More adjustments are available when using the eLink mobile app.
SmartPlus
®
Recirc Logic:
SmartPlus adds intelligence to your system by learning when hot water is
used in the home. The pipe-mounted sensor records daily hot water usage patterns during the
course of the week. Recorded data is used to automatically run the circulator at the same times the
following week. So hot water is always available when it is needed. If usage pattern changes, the
SmartPlus adjusts automatically.
“Smart” Mode
(default mode): the SmartPlus logic will run in Pulse mode as described below
for the first 7 days of operation. During the first 7 days, the SmartPlus logic monitors and
records the home's hot water usage pattern. For the following 7 days, the SmartPlus logic will
use the preceding week's usage pattern to cycle the pump during the recorded hot water usage
times. This process of recording and repeating is continuous, and automatically adjusts the
pump "ON" times to match the house hold's usage pattern.
“Pulse” Mode:
When set to Pulse mode, the SmartPlus logic will cycle the circulator pump "ON"
for 5 minutes, then “OFF” for 10 minutes to maintain hot water at all faucets and taps. It will
repeat the cycle continuously.
More adjustments are available when using the eLink mobile
app.
When a sensor is connected to the Recirc sensor input, zone 2 output will now be designated for
recirculation of DHW loop and activated based on DHW usage.
