Optional Equipment - NTI FTVN085 Installation Start-Up Maintenance

condensate should be neutralized to avoid damage to the drainage
system or piping.
Outdoor Sensor
Monitors outdoor temperature and adjusts unit set point to provide
greater efficiency.
0-10 Volt Input / 4-20 mA Input (with Optional Analog Clip-In
Board, part # 3319457)
Allows the installer to connect a BMS (Building Management System)
to control the boiler.
Condensate Trap
The condensate trap prevents condensate and heat exchanger exhaust
from backing up into the boiler.
Pump Service Mode
Allows manual operation of pumps to commission system and check
pump operation.
Internal By-Pass Valve
Protects the boiler from damage in low flow conditions.
Internal ECM Pump
The internal ECM Pump uses less electricity than standard pumps,
providing high performance operation.
DHW Temperature Sensor
Monitors DHW outlet temperature. The control adjusts boiler firing rate
to match the DHW supply temperature to the set point.
DHW Flow Meter
Monitors DHW flow rate.
