Products
-
COC - DIGI-SPAN® This series of controls senses temperature, pressure, or humidity and provides two outputs, one reverse acting, and one direct acting. -
EPU
EPU-CHEffectively regulates the ambient indoor temperatures according to outdoor temperature. The heating system is shut down when the outdoor temperature rises above an adjustable set point. -
HWE
HWE-MOV
HWE Multi StageThe perfect control for residential and light commercial Hot Water Reset applications. All of the Elite Series controls come with a digital display, adjustable reset ratio, offset and outdoor cutoff. HWE/Single Stage - Hot Water Reset control with or without domestic hot water priority for single stage boiler applications. Replaces the HWM 100
HWE/MOV - Provides Hot Water Reset by modulating a 3 or 4 way motorized valve. Replaces the HWM 200
HWE/Multi Stage - This control provides Hot water Reset control for multi-stage applications. Controls up to 4 Stages (4 on/off or 2 lo/hi) or when combined with an SEQ 6 or 12 it combines up to 16 stages. Replaces HWM 550.
-
HWR/HWR-Q The HWR will start and stop the boiler or open/close a motorized valve, to vary the system water temperature into the buildings radiation in accordance with outdoor temperature. * The HWR-Q varies the system water temperature in accordance with outdoor temperature, by controlling up to 4 boiler Stages (4 on/off or 2 lo/hi). Additional stages can be added with an SEQ control.
-
Injectemp® The InjecTemp® is a complete passive injection SYSTEM for radiant and other types of hydronic heat. The control provides indoor/outdoor reset, secondary pump control, and a boiler start signal. The InjecTemp® system uses standard components, is easy to pipe, and automatically provides comfortable levels of heat. As the outdoor temperature drops, the InjecTemp® will activate the heating system, and adjust the temperature of the circulating heating water to maintain constant indoor air temperatures. -
MCA - DIGI-SPAN®
MCF - DIGI-SPAN®
MCP - DIGI-SPAN®
This series of controls senses temperature, pressure, or humidity and provides either a Floating output (MCF), a Proportional 0 to 135 ohm output (MCP), or a Proportional 0 to 10 V or 4 to 20mA output (MCA). -
Motorized Valves
T wo-Way (2" to 10")2-Way valves can turn ON or OFF the flow of steam from the boiler or other source into a steam distribution system. A typical example of this type of application would be using steam to heat radiators in a building. Another use would be modulating the quantity of steam entering a heat exchanger. When the load changes, the valve is signaled to change the amount of steam entering the heat exchanger. -
Motorized Valves
Three-Way (1" to 8") Three-Way Radiant
(1/2" to 2")3-way valves are used to mix water to a desired temperature. The hot water from the boiler is blended with a proportion of the cooler water returning from the system to maintain the correct water temperature entering the system. Note: These valves can also be used in diverting applications. -
Motorized Valves
Four-Way Radiant
(1/2" to 4")The Heat-timer Radiant Valve is designed to provide superior control and reliability. The valve is primarily designed for use in Commercial and
Residential Hot Water Heating Systems, controlling the temperature of a zone. -
MPC/MPC-Q The MPC will start and stop the boiler, or open/close a motorized valve, to vary (cycle) the duration of steam flow into a building's radiation in accordance with changes in outside temperature. The colder it is outside, the more steam that is allowed to enter the building. * The MPC-Q varies the duration of steam flow into the buildings radiation in accordance with changes in outdoor temperature by controlling up to 4 boiler Stages (4 on/off or 2 lo/hi). Additional stages can be added with an SEQ control.
-
Multi-Mod The MultiMOD is the perfect control whenever multiple fully modulating stages are required for heating or cooling. The MultiMOD can sequence up to 4 fully modulating stages for Temperature or Pressure Applications. An Extension Module can be added to control up to 12 stages. -
Precision Tempering Valves 1/2" to 4" Heat-Timer tempering valves are designed to handle all flows from low to peak automatically without any extra effort. Precise water temperature control makes it ideal for Hotels, Hospitals, Health Care facilities, Schools, Apartment, Office and Industrial Buildings. -
RSM The Heat-Timer RSM is designed to control under slab heating systems used to melt ice or snow in Residential applications. It can be used in driveways, staircases, sidewalks, or other locations, which must be kept clear on snow or ice. The RSM will activate the slab heating system when the outdoor temperature is low enough that ice or snow could form. -
SCP The SCP is designed to be used with multiple hot water boiler systems that require the control of individual boiler pumps that require pump run on. In addition, the SCP can provide an interlock to combustion air, and/or a lead-lag function of two primary circulator pumps. The SCP control is designed to be used as an interface between a boiler sequencing control such as a Heat-Timer HWR-Q and the boiler and pumps. The SCP panel will control up to four boilers, four boiler secondary pumps, two primary pumps in lead/lag mode, a combustion air damper/fan, a combustion air damper/fan interlock, and an alarm output. -
SEQ 6
SEQ 6P
SEQ 12
SEQ 24
The SEQ is the perfect control whenever multiple stages are required for heating, cooling or humidity applications. The SEQ will automatically activate as many stages needed to maintain precise setpoint control using P.I.D logic.
* The SEQ 6P provides an additional output for each boiler pump, which can remain active for an adjustable time delay. -
SMC The Heat-Timer SMC control is designed for under slab heating systems utilized for snow and ice melting. It can be used in applications such as driveways, runways, staircases, walkways, train/monorail stations, racetracks, etc. It senses slab temperature, the absence or presence of precipitation, slab water supply and return as well as boiler water return temperature. -
SPC - DIGI-SPAN®
SPC TEMP - DIGI-SPAN®The SPC (set-point control) series senses temperature, pressure or humidity and provides a S.P.D.T (single pole, double throw output.) It is used whenever on/off or two-position control is desired. -
SRC The SRC is an outdoor reset control for sub-atmosphere steam systems. The SRC will start/stop the vacuum pump and boiler, and modulate the steam valve to vary (cycle) the duration of seam flow into a building's radiation in accordance with changes in outside temperature. -
TSC - DIGI-SPAN®
TSR - DIGI-SPAN®This series of controls senses temperature, pressure, or humidity and provides two Normally Open outputs. These outputs can be field configured for direct or reverse acting control -
TMC The Temperature Monitoring Control (TMC) is ideal for any application that requires vigilant system monitoring. -
Adjustable Radiator and Main Line Vent Valves for One Pipe steam Systems. Because Heat-timer VARIVALVES vent so quickly, it takes less time to fill your system with steam. And by adjusting the venting to balance the system, there is no need to raise the steam pressure to reach under heated areas. Shorter boiler run times and lower pressure results in fuel savings. A large easy to adjust variable orifice simplifies balancing and makes radiators heat up fast. -
VSP The VSP is ideal for most radiant or residential and light commercial hydronic heating. The VSP adjusts the speed of the pump to accurately control the amount of hot water injected into the heating loop. The VSP can be used as a hot water reset or single set point control. -
ZCP The ZCP is designed to work with multi-zone hydronic heating systems that may include radiant and/or baseboard and/or other types or radiation. The panel is pre-wired and can activate either zone valves or zone pumps or a combination or both. If any zone calls, the boiler output is activated. The ZCP can a built in selectable Domestic Hot Water Priority. ZCPs can be cascaded together to provide as many zone outputs as are needed.
