Modulating Fan Coil Thermostats

Description

The SZ1060 Series is designed for fan coil
applications that require digital (SZ1061 and
SZ1062) or modulating (SZ1063 and SZ1064)
heating and/or cooling.

Features:

• Stand-alone or network operation
• P+I control option (SZ1061 and SZ1062 only)
• No battery backup required
• Minimum on/off times for HVAC equipment
protection
• 32-character LCD display
• Six status LEDs
• Remote room sensing capability
• User setpoint adjustment limits
• Three speed fan
• System and fan switching with access lockouts
• External input for setback or aquastat changeover
• Access to programming may be locked out or
limited with the use of an access code
• Fahrenheit or Celsius temperature display
• Control for two or four pipe systems
Additional features on SZ1062 and SZ1064:
• 7-day programmable time clock
• Optional pipe sensor input for changeover
• Adjustable delay on start-up and power-up for
soft starts
• Smart recovery
• Local and remote override capability
