6.6.4.1.b Heating Demand, Smart Grid 2
6.6.4.1.c Heating / Cooling Circuit (HCC) Circulation
Pump (M13)
The Heating Demand, Smart Grid 2 contact can be used for two functions:
1. Used as a normally closed thermostat connection to activate the
setpoint heating mode. When using an air handler this mode should be
utilized for better operation, increased efficiency, and comfort delivery.
2. As a utility (demand response) signal to lower the DHW tank to
minimum temperature
For additional functionality and settings see Smart Grid section in the User-
interface programing instructions
Using option 1, helps with short cycling and extends runtimes since the
buffer tank is charged with a lower temperature.
The Heating / Cooling Circuit (HCC) Circulation Pump (M13) is a field
supplied pump which can be controlled as part of the System M operation
through a 0-10vDC signal (terminal 12 & 13). The circulator must be able
to accept a 0-10vDC signal, such as the Taco 0034e, VR3342, VR15-30,
or 00-VV products. Using this circulator as the primary loop pump for the
heating / cooling circuit (HCC) optimizes the operation of the system and
provides integrated control, such where on a domestic hot water call it will
turn the pump off so full hot water is delivered to the DHW tank with priority.
Power to the HCC pump (M13) is field supplied. (See figure 12 and section
6.6.1) (See figure 12 & 13)
6.6.5 Electrical Connection for the Indirect Hot
Water Tank
If using the mating Taco 85-gallon indirect hot water tank, model SMT85-
1 tank: 120 VAC power should be run to a field supplied and wired 30
AMP, 2-Pole contactor. The contactor can be installed in the black wiring
enclosure on the DHW tank. 240 VAC (30A input) needs to be run to the
other side of the contactor and attached to the DHW immersion heater.
A DHW call is activated by the supplied sensor field-installed in the thermal
well in the SMT85-1 DHW tank (see section 6.4). Field wiring is required
between the HydroBox indoor unit wiring hub, terminals 6 & 7, and the DHW
tank sensor.
If using another indirect hot water heater or electric boiler for the production
of domestic hot water: The output signal to the indirect from the HydroBox
is 120VAC. Depending on the type and style of DHW tank, separate
contactors may be required to properly operate the tank or boiler properly.
Consult the specific equipment manufacturers instructions for operation,
detailed wiring, and safety warnings.
6.6.6 LAN / Network Connection
6.6.7 Factory Wired Components
7.1 Installing the Dimplex Home App
The heat pump is only designed for connection to the internet via a
router. This ensures that the user can access the system at any time for
setting parameters or for reading out system status or fault information.
This connection is required for system monitoring, and operational/safety
software updates.
A conventional LAN network cable is required for connection, which is
connected between an external router (+A350) and the LAN plug on the
back panel of the HydroBox indoor unit. (See section 11)
The heat pump circulating pump (M16) and domestic hot water tank
circulating pump (M18) are powered with 120v and designed to be operated
in variable speed mode, controlled through a 0-10 VDC signal. Both
circulator pumps are Taco 0034e-SF.
A temperature sensor is installed in the return line before going out to the
heat pump.
Search for “Dimplex Home” within the App Store or Google Play on your
smart device or mobile phone. Download and install the app. Once
complete, you must register the app. Once registered, log into the app.
Make sure your smart device and the System M has a good internet
connection. The HydroBox indoor unit should be connected directly to a
router using a Cat 6 ethernet cable plugged into the back of the indoor unit.
To synch your app and System M unit, go through the following steps at the
HydroBox’s touch screen display:
• The default display is a clock, showing the date and current outdoor
temperature. Touch anywhere on the screen to begin.
• Drawn a “M“ pattern starting from the bottom left
dot to access the general menu and settings
• You are now at the Home screen. Swipe down,
starting from the cog icon at the top of the Home
screen to access the main Settings screen.
6.6.4.1 Optional Wiring Connections
6.6.4.1.a Forced Cooling Change-Over
Forced cooling uses a normally closed
dry contact signal to activate the cooling
function during times where the outdoor
temperature is in a dead band area
(between the set ranges for heating and
cooling operation). It allows for cooling to
be activated across the entire operating
limits (see figure 18) (Terminal 9 and 10).
This function is recommended to be used
in a single zone air handler system so if
there's large solar gain or other temporary
changes (i.e. gathering or party) the system
can activate a cooling demand even while
the outdoor temperature is below the cooling
start range (in the dead band area).
