Field wiring
J. 0–10 VDC Remote TARGET input –
Terminal Block P15 #5 & #6 (SlimFit control module, left side)
1. See illustration at right and Figure 18, page 32 (wiring diagram) for details.
2. Remote target using 0–10VDC input requires a 0–10VDC input signal at
P15-5/6 as shown at right.
a. The input positive connection must be at P15 terminal 6 and the common
connection at terminal 5.
b. Using PRIORITY 1, 2, or 3 for single boiler, or LOCAL PRIORITY 1 or
LOCAL PRIORITY 2 for a network boiler.

c. Using NETWORK PRIORITY 1 or NETWORK PRIORITY 2 for a net-
work boiler. The 0–10VDC input must be made

of the network
3. The illustration at right also shows how to connect TT or end switch contacts
at INPUT 1, INPUT 2 and INPUT 3 of any boiler.
a. If the target controller has a heat demand contact, connect it to one of
the INPUTs and set up in the WIZARD or manually.
4. The 0–10VDC signal is used to adjust the supply target temperature, using
the TARGET ADJUST setting. Set TARGET ADJUST during the WIZARD
or manually in the setup menu for the priority chosen.

Suggested 0–10VDC remote target setup for single boiler or a local
:
priority
a. Use PRIORITY 1 (or LOCAL PRIORITY 1) for the DHW heating circuit
when used. This priority's default values are set for DHW, direct-connected
to the boiler. Verify that settings are suitable for the application, chang-
ing if needed.
b. Use PRIORITY 2 (or LOCAL PRIORITY 2) for the heating circuit that
uses the 0–10VDC input.
•
For single boilers, the factory default settings for either of these pri-
orities make them a good choice for space heating applications. Set
priority values to the following:
•
Set TARGET ADJUST value to 0–10V.
•
Set VOLTS FOR MAX at the voltage that will call for the highest target
temperature. Set SUPPLY MAX at this temperature.
•
Set VOLTS FOR MIN at the voltage that will call for the lowest target
temperature. Set SUPPLY MIN at this temperature.
•
For voltages between VOLTS FOR MAX and VOLTS FOR MIN, the
target temperature will range proportionately between SUPPLY MAX
and SUPPLY MIN.
•
NOTE: The 0–10VDC signal replaces the ODT sensor as the target
temperature modifier (TARGET ADJUST setting). The SlimFit control
does not control target.
6.
Suggested 0–10VDC remote target setup for a network priority:
a. Setup the control as above, but select NETWORK PRIORITY 2 for the
heating circuit that uses the 0–10VDC input..
b. If a local (direct-connected) DHW circuit is used, select LOCAL PRIOR-
ITY 1 for DHW. If a DHW circuit in the system is used, select NETWORK
PRIORITY 1 for DHW.
