Heat-Timer Corporation offers a complete line of controls
for the HVAC/R and Plumbing Industry. Over 60 years of experience insures
that Heat-Timer specifically designs, tests and builds energy efficient
control systems which are easy to install and use, and which provide maximum
comfort.
HWR/HWR-Q
Applications:
 The
HWR/HWR-Q model is for hot water heated buildings. The HWR/HWR-Q will start
and stop the boiler, or modulate a motorized valve, to vary the system water
temperature into a building's radiation in accordance with changes in
outside temperature. The colder it is outside, the hotter the water which
will circulate through the building. The HWR/HWR-Q can be upgraded for
remote communications allowing the HWR/HWR-Q to be monitored and adjusted
from any computer with a modem.
Features:
- Adjustable outdoor temperature cutoff
- Adjustable reset ratios and offset
- 8 separate Day/Night adjustments for each day of the week
- Multiple setback schedules
- Optimum variable boost (Morning warm-up)
- Adjustable minimum water temperature
- Battery backup of program
- Solid state circuitry
- LED digital displays
- Self diagnostics
- Remote communication option (field upgradeable)
- Johnson Metasys® compatible
- Locking NEMA-1 enclosure
- Solid state sensors can be extended up to 500' from the control
- Accuracy of ±1ºF or 1% of full scale
Multi-Mod
Applications:
 The
Multi-Mod smoothly controls multiple stages of full modulation burners.
It's patented design and computer logic allows the system to bring on
just the amount of modulation necessary to hold the desired set point.
The Multi-Mod can control either temperature or pressure systems, and
can be field configured for heating or cooling applications. The
Multi-Mod can be upgraded for remote communications allowing
it to be monitored
and adjusted from any computer with a modem.
Features:
- Only one sensor is required (regardless of the number of stages
being controlled)
- Digital display of: System temperature or pressure, system set
point, control parameters
- LED display of percent modulation of each stage
- Manual overrides for each stage
- Automatic or manual lead stage rotation
- Can be cascaded to provide as many stages as needed
- Plug-in relays
- RWB mod motor output and N.O. contacts for each stage
- Remote communication option (field upgradeable)
- Johnson Metasys® compatible
- Can be field configured for heating or cooling
- Can be field configured for setback (from external clock,
temperature sensor, aquastat, etc.)
- Temperature Multi-Mods can be configured to input a 4-20mA signal
from an EMS system
- Locking NEMA-1 enclosure
- Solid state sensors can be extended up to 500' from the control
- Accuracy of ±1ºF or 1% of full scale

Mini-Mod
 The Mini-Mod is the
perfect control whenever multiply fully modulating stages are required for
Hydronic heating applications. The Mini-Mod controls the on/off and
the modulation of each stage (up to 4) to maintain precise set point control
using PID type control logic.
Features:
- Only one sensor is required (regardless of the number of stages
being controlled)
- Digital display of: System temperature, system set
point, control parameters
- The option of using outdoor reset, set point,
or receive and external set point from an EMS/BMS system as 4-20mA
(requires use of 4-20mA EMS interface)
- Display of percent modulation of each stage
- Manual overrides for each stage
- Automatic or manual lead stage rotation
- Can be cascaded to provide as many stages as needed
using up to two Mini-Extensions Panels (each can control up to 6
boilers) up to a total of 16 boilers
- RWB mod motor output (0-5V, 0-10V, 1-5V, 2-10V
& 4-20mA) and N.O. contacts for each stage
- Can be field configured for setback (from external clock,
temperature sensor, aquastat, etc.)
- Domestic Hot Water capability with optional
priority
- Locking NEMA-1 enclosure
- Solid state sensors can be extended up to 500' from the control
- Accuracy of ±1ºF or 1% of full scale
