CHAPTER 13 - EXTERNAL MODULATING CONTROL
The INSTINCT can directly accept an analog
0-10 VDC signal from an external modulating boiler
controller to control the firing rate.
13.1. Wiring the Modulating Controller
Run two 18 gauge wires from the external modulating
boiler controller’s 0-10 VDC boiler output to low voltage
terminals X5-1&2 located at the bottom of the CTRL-
Max control module, as shown in
Fig. 31 on page 47.
This signal will both enable and modulate the boiler. No
wiring is required at the thermostat terminals.
External modulating control will only function if the
external modulating controller is properly wired to the
INSTINCT as follows:
• X5-1 = +
• X5-2 = -
Ensure that the polarity of the connections
from the external modulating boiler controller
to the boiler are correct. Reversed polarity will
lead to no response from the boiler.
NOTICE
13.2. CTRLMax Programming
The CTRLMax control module must be programmed to
accept the 0-10 VDC signal from the external modulat-
ing boiler control.
1. Use the Heating EZ
Setup function to set
CH Demand to 0-10V Modulation Signal. Reference
Section 9.7 on page 54.
13.3. Programming of External Modulating
Control
The external modulating control must be programmed
to send 2 VDC to enable the boiler and run it at low fire,
and 10 VDC to run the boiler at high fire. Once the con-
trol enables the boiler, it must wait 30 seconds to allow
the burner to stabilize before modulating the boiler.
